Introduction

WELCOME ABOARD!
hanks for choosing the VOX AD15VT, AD30VT, AD50VT or AD100VT Valvetronix amp. To ensure a long and trouble-free relationship with your new amp, please read this manual carefully, use the amp as directed and keep the manual for future reference.

MAIN FEATURES

The AD15VT, AD30VT, AD50VT and AD100VT use Valve Reactor technology, and feature a power amp circuit containing a 12AX7 (ECC83) dual triode valve (vacuum tube) that would normally be used in a preamp. This allows the amp to produce the true sound and feel of a bona de all valve (tube) amp. Sophisticated modeling technology is used to provide eleven different amps. They range from classic vintage amps of the past to current expensive high-end valve amps, and are accessible at the turn of a knob. Eleven high-quality effects are built in and seven are multi effects that let you use two effects simultaneously plus Noise Reduction. You can store your favorite amp and effect settings as a program, which contain two different settings (CH1 and CH2). You can switch between these settings from the top panel, or by using the optional VFS2 foot switch connected to the rear panel (Channel Select mode). In addition, theres one preset program for each amp type (Preset mode). In Manual mode the sound you hear will reect the physical settings of the knobs. If you connect the optional VFS2 dual foot switch (sold separately*), you can use it to switch programs or bypass effects. The power level control (The AD15VT doesnt have this feature.) lets you adjust the output wattage of the power amp. This means that even when the master volume is turned up to the max to drive the Valve Reactor power amp, you can adjust the volume without losing any tone. The external speaker out jack (AD50VT/AD100VT only) lets you connect a guitar speaker cabinet (8 ohm) of your choice. The effect send/return jacks (AD100VT only) allow you to connect your external effect processor in a loop connection.

NOTE: Connecting headphones to this jack will mute the internal speaker.
EXTERNAL SPEAKER OUT jack You can connect a guitar speaker cabinet to this jack.
NOTE: Sound will not be output from the internal speaker if you use the external speaker jack. NOTE: The AD15VT and AD30VT dont have this jack. Important: To ensure that your system works correctly, you must observe the following points. a) Dont use an external speaker whose impedance is other than 8 ohms. b) Dont connect a speaker whose rated input capacity is less than 50 watts (100 watts for the AD100VT). The speaker may be destroyed if you ignore this caution not recommended! c) You must use a speaker cable to connect an external speaker. Dont use a shielded cable like the one you use to connect a guitar to an amp. d) You must turn off the power before connecting the cable. Connecting the cable while the power is turned on may damage your amp.
These jacks let you connect an external effect loop. SEND jack Connect this to the input of your external effect unit. RETURN jack Connect this to the output of your external effect unit.
About the three operating modes
he AD15VT/AD30VT/AD50VT/AD100VT contains eleven preset programs. To select one of these, enter Preset mode (which simply means, press the PRESET button) and turn the AMP selector.
There are also two rewritable channel programs which you can select by pressing the CH button or by using the optional VFS2 foot switch.
PRESET MODE (SELECTING A PRESET PROGRAM)
In Preset mode, simply turn the AMP selector to select a preset program that contains typical settings for each amp type. The GAIN, VOLUME, TREBLE, MIDDLE, BASS, and effect settings will switch automatically.

GETTING TO PRESET MODE

If the PRESET LED is dark, youre not in Preset mode. Press the PRESET button to make the PRESET LED light.
NOTE: If the CH1 or CH2 LED is blinking (i.e., when youre in the middle of selecting a writing-destination for the program) the PRESET LED wont light when you press the PRESET button the rst time. In this case, just press the PRESET button once again.
SELECTING A PRESET PROGRAM
With the PRESET LED lit, turn the AMP selector and the preset program for each amp type will be selected. (The physical settings of the top panel control knobs and EFFECTS selector are ignored at this time.)
HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, the effect is bypassed. Press the BYPASS button once again to cancel bypass and enable the effect once again. The AD15VT, AD30VT,AD50VT & AD100VT remembers the bypass setting even if you switch modes or programs, or turn off the power.
CHANNEL SELECT MODE (SELECTING A CHANNEL PROGRAM)
In Channel Select mode you can press the CH button to recall the program saved in each channel (CH1 and CH2), automatically switching all of the amp and effect parameters.

GETTING TO CHANNEL SELECT MODE
If the CH1 and CH2 LEDs are dark, youre not in Channel Select mode. Press the CH button. Either the CH1 or CH2 LED will light, and youll be in Channel Select mode.
NOTE: If the CH1 or CH2 LED is blinking (i.e., when youre in the middle of selecting a writing-destination for the program), the program wont switch when you press the CH button the rst time. In this case, press the TAP button to stop the blinking.

SWITCHING CHANNELS

With either the CH1 or CH2 LED lit, press the CH switch. The channel will change each time you press the button, and the program stored in each channel will be recalled. (The physical settings of the top panel selector knobs and control knobs are ignored at this time.)
HINT: If the optional VFS2 dual foot switch is connected to the rear panel, you can use it to switch programs. For details, refer to Using the VSF2 dual foot switch (page 16). HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the LED. The AD15VT, AD30VT,AD50VT & AD100VT remember the bypass setting even if you switch modes or programs, or turn off the power.

MANUAL MODE

When the AD15VT, AD30VT, AD50VT or AD100VT is in Manual mode, it works just like a non-programmable guitar amp. In other words, the positions of all top panel selectors and knobs (except for the EDIT 1 knob) indicate exactly what youre hearing.

GETTING TO MANUAL MODE

If the MANUAL LED is dark, youre not in Manual mode. Press the MANUAL button; the MANUAL LED will light, and youll be in Manual mode.
NOTE: If the CH1 or CH2 LED is blinking (i.e., when youre in the middle of selecting a writing-destination for the program), the MANUAL LED wont light when you press the MANUAL button the rst time. In this case, simply press the MANUAL button once again. NOTE: In Manual mode when you edit parameters that arent dened by a knob setting (i.e., effect parameters or noise reduction settings), those settings are saved automatically, and will be recalled the next time you enter Manual mode. However if the EFFECTS selector is at a different position than it was when you were last in Manual mode, the default settings for that effect type will be loaded. HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the LED. The AD15VT, AD30VT,AD50VT & AD100VT remember the bypass setting even if you switch modes, programs, or turn off the power.Creating and storing your own program

Creating and storing your own program
here are two ways you can do this; by tweaking an existing preset program thats close to what you have in mind, or by starting from scratch.
CREATING YOUR OWN PROGRAM
Lets start from scratch. 1. Choose any program in Preset or Channel Select mode, or select Manual mode.
HINT: Since were starting from scratch it doesnt matter what program you choose.
2. Use the BYPASS button to bypass the effect. (The BYPASS LED is lit.) If you want to use an effect, you can add it at the end of this process. 3. Use the AMP selector to select the amp you want to use.
HINT: For details on the amp types, refer to Amp models and effects (page 17).
4. Adjust the top panel GAIN, VOLUME, TREBLE, MIDDLE, and BASS knobs as desired. 5. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise reduction. This setting is also saved as part of your program. For details, refer to Adjusting the noise reduction (page 13)
HINT: Adjust the noise reduction so that you dont hear noise when youre not playing your guitar.
6. If you want to use an effect, press the BYPASS switch once again to turn bypass off (the BYPASS LED goes dark). 7. Select an effect, and make adjustments. For example if you want to add delay, turn the EFFECT selector to DELAY. If the selector is already set to DELAY, youll have to turn it to a different effect and then back to DELAY. Use the TAP button or EDIT 1 knob to adjust the delay time and delay level (the amount of delayed sound). DELAY TIME: DELAY LEVEL: DELAY FEEDBACK: Press the TAP button twice (at the desired interval), or hold down the TAP button and turn EDIT 1. Turn EDIT 1 (without pressing any button). Turn EDIT 1 while holding down the BYPASS button.
HINT: For details on the effects, refer to Amp models and effects (page 17).
8. When youve come up with a sound you like, store the program.
NOTE: In Preset or Channel Select mode, the changes you made will be lost if you switch to a different program or Manual mode or turn off the power without storing the program rst. NOTE: The effect bypass setting isnt stored as part of the program.
ADJUSTING THE NOISE REDUCTION
Heres how to adjust the noise reduction
HINT: When using a high-gain amp model such as NUMETAL or US HIGAIN, we recommend that you use noise reduction, since more gain means more noise! NOTE: The noise reduction setting is part of each program. In Preset and Channel Select modes, your setting will be lost if you switch to a different program or to Manual mode (or turn off the power) without storing your edited program rst.

1. Press the BYPASS button to make the BYPASS LED light. 2. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise reduction sensitivity. Turning the knob toward the right will produce greater noise reduction (less noise). If you turn the knob all the way to the left, noise reduction will be off, and wont do anything (more noise).
NOTE: Depending on the guitar youre using, excessively high noise reduction settings may cause notes to be cut off in an unwanted manner!
3. If you want to use effects, press the BYPASS button to make the BYPASS LED go dark and the effect(s) will be heard.

STORING YOUR PROGRAM

When youve come up with a sound you like, you should store (write) the program. 1. Press the WRITE button. The CH1 or CH2 LED will blink. 2. Press the CH button to select the channel in which you want to store your program. The program will be stored in the channel whose indicator is blinking.
HINT: If, during this process, you decide that you really dont want to store the program, you can press the TAP button to cancel at this point. The LED will stop blinking, and youll return to the mode in which you were.
3. Press the WRITE button once again. Your program will be saved in the specied channel, and the LED of the destination channel will stop blinking and remain lit.
NOTE: The program that was previously stored in that channel will be overwritten; in other words, the settings that used to be stored in the channel you selected in step 2 will be erased. NOTE: The effect bypass setting isnt stored as part of the program. NOTE: If youre creating your sound in Preset or Channel Select mode, your changes will disappear if you switch to a different program or to Manual mode before storing.
CHECKING THE SETTINGS OF A PROGRAM (ORIGINAL VALUES)
If you want to nd out exactly what settings are saved in a preset or user program, you can use the Original Value function. When youre turning a knob to adjust the value of a parameter, and the value at that moment matches the value that is saved in the program (i.e., the original value), the PRESET LED will blink if youre in Preset mode, or the channel LED will blink if youre in Channel Select mode.
HINT: When youve found a program you like, and want to know just what settings it contains, simply use this Original Value function! NOTE: The settings of the top panel MASTER volume and the rear panel POWER LEVEL controls arent part of the program, which means that the Original Value function isnt available for these knobs. Also, the Original Value function doesnt operate in manual mode.
RESTORING THE FACTORY SETTINGS
Heres how you can restore the factory settings.
NOTE: If you do this, the programs you saved in the channels will be completely erased, and will be reset to the factory settings. NOTE: Effect and noise reduction settings made in the Manual mode will also be erased.

1. Turn the power off. 2. While holding down both the CH and WRITE buttons, turn the power on. When the CH1 and CH2 LEDs begin blinking, release these two buttons.
HINT: If you decide to abort this operation, press the TAP switch at this point.
3. When you press the WRITE switch, the CH1 and CH2 LEDs will change from blinking to lit. Initialization will be completed in a few seconds, and the amp will switch to Preset mode.
NOTE: Never turn off the power while initialization is taking place.
Using the VFS2 dual foot switch
f the optional VFS2 dual foot switch (sold separately*) is connected to the rear panel FOOT SW jack, you can use it to switch programs or turn effect bypass on/off.
VFS2 left switch (switch 1): Switches channel programs VFS2 right switch (switch 2): Switches bypass on/off, or turn Manual mode on
SWITCHING THE CHANNEL PROGRAM (SWITCH 1)
Each time you press the VFS2s left switch (switch 1), youll alternate between CH1 and CH2.
NOTE: Switch 1 has the same function as the channel select switch on the top panel. If you press switch 1 in Preset mode or Manual mode, youll change over to Channel Select mode. Also, pressing switch 1 during the process of storing a program (the CH1 or CH2 LED is blinking) will change the store-destination.
TURNING EFFECT BYPASS ON/OFF (SWITCH 2)
Hold down the top panel BYPASS switch and press the VFS2s right switch (switch 2). This assigns the function of switch 2 as bypass on/off. Now when you press switch 2, effect bypass will alternately be turned on/off.
HINT: The amp will remember the switch 2 assignment. This setting is remembered even if you switch modes or programs, or turn off the power.
SWITCHING TO MANUAL MODE (SWITCH 2)
Hold down the top panel MANUAL switch and press the VFS2s right switch (switch 2). This assigns the function of switch 2 as Manual mode. Now when you press switch 2, the amp will switch to Manual mode.

Amp models and effects

In this section were going to talk about the eleven amp models and effects.

AMP MODELS

hich amps did we painstakingly model for our selection of eleven? Believe me when I say it wasnt easy cos, as Im sure you know, theres a plethora of greatsounding amps out there. After countless hours of soul searching, earnest discussions (not to mention the occasional friendly argument!), calls to tone-wise friends (some professional players, some not. but all blessed with great ears) plus, of course, listening and playing, a top eleven list was nally drawn up. As youre about to discover, the ones we went with are not only the cream of the crop but also offer up the widest possible array of the greatest guitar tones known to man from pristine clean to outrageous overdrive and all points in-between.

CONTROLLING FACTORS

As already touched on in this manual Guitarists Guide although the top panel of your Valvetronix amp houses controls for TREBLE, MIDDLE, BASS, GAIN, VOLUME, and MASTER, not all of the amps weve modeled have as many controls. In such cases, rather than leave you with knobs that do nothing, weve made full use of all ve Valvetronix amp controls without compromising the accuracy of any of our models. This means youll be able to mimic the full tonal spectrum of each and every one of the originals weve modeled. and then some, thanks to the extra exibility and additional control the ve Valvetronix amp controls give you. For example, if an original doesnt have a Gain Control (AC15, AC30TB, UK 70S, BLACK 2x12, and TWEED 4x10), the Valvetronixs GAIN control will mimic the originals Volume control. This, of course leaves you with three volume controls to use; VOLUME, GAIN, and MASTER. As you already know, MASTER is a universal, non-programmable control that allows you to set the overall volume of the amp. So, the programmable VOLUME control (the knob right next to GAIN) effectively acts as a second Master Volume, allowing you to ensure that the volume of each of your programs compliments the rest. Cool stuff, Im sure youll agree. Also, if an original amp doesnt have a complete 3 band EQ network then well set up the missing tone controls on our model to be neutral (i.e. as the original) when set at 12 oclock thus giving you extra tonal exibility in those EQ areas, if you so wish. Just so you know, the amps we modeled that dont have individual controls for Treble, Middle and Bass are:

Bass Cut switch

Treble and Bass controls

TUBE TALK

Us Brits call em valves while our US cousins call em tubes. as the saying goes: England and America are merely two countries divided by a common language! Anyway, call em what you will, these wondrous glass bottles lie at the tonal heart of each of our 11 models. As all the amps weve modeled hail from one of the two countries just mentioned, in honor of their heritage, the descriptions of all English amps will employ the words valve and valves, while the American ones will be tubular!
QUESTION: Whats the difference between an ECC83 preamp valve and a 12AX7 preamp tube? ANSWER: Nothing! Theyre the same exact thing namely the most popular preamp tube in ampland. ECC83 is the British name, 12AX7 (a.k.a. 7025) is the American.

POWER AMP ACCURACY

As already touched on a couple of times, what happens in the power stage of any good tube amp is of paramount importance to the way the amp sounds, feels and behaves. The way the power amp operates (Class A or Class AB), the power tubes used (EL84s,EL34s, 6L6s, 6V6s), the exact nature of the negative feedback loop circuitry, and how the power stage interacts (a relationship called damping) with the speaker(s) it is driving all these things play a vital role in the creation of tone. And, thanks to our patented in USA Valve Reactor Technology all these important bases are faithfully and accurately covered. For example: if you choose the amp model AC30TB an amp with a Class A power stage and no negative feedback thats exactly what your Valve Reactor power amp recongures itself to emulate. And, as an added bonus, thanks to our rear panel POWER LEVEL control you can adjust the output power (Wattage) to best suit the size of the room youre playing in. (The AD15VT doesnt have this feature.)

TURN IT UP!

Truly great, all-valve amps have one thing in common they invariably sound at their best when theyre cranked to the max! Its got nothing to do with eardrum shattering decibels either; its just that when the power valves are driven hard, they denitely impart a unique tone and width to the overall sound. Thanks to the awesome accuracy of our Valve Reactor power amp, the same is also true of your Valvetronix combo. For this reason, we heartily recommend that you crank the sucker up as often as possible. And, as already pointed out, thanks to our unique POWER LEVEL control (not provided on the AD15VT), you can adjust the output Wattage to suit every occasion from bedroom, to garage, to gig. and all points in-between. So, what are you waiting for select, crank and enjoy! This all said, lets take a look at each of our amp models.

1. BOUTIQUE CL

For this amp type, we modelled the Clean channel of a very rare, very expensive and respected 100 Watt head named the Overdrive Special. We auditioned several top-shelf boutique amps for this model but this amp was the clear winner. Its beautifully rounded low-end, delightfully transient mid-range attack and sweet treble make it the perfect partner for single- coil pickups. It is also incredibly responsive and extremely sensitive to picking styles and pickup selection. Strummed chords just ring out and blossom.
Originals tube compliment: 3 x 12AX7s in preamp, 4 x 6L6s in power amp.

2. BLACK 2x12

This dual channel, blackfaced beauty is considered a must- have 2x12 combo for many professionals. Its celebrated clean sound is very tight n twangy, with a deep, taut, piano-like bass. Pristine clean tones aside, BLACK 2x12 is also capable of producing that classic Chicago blues tone especially with single coil pickups. In keeping with the original, when pushed hard the bass tends to crumble so raise the MIDDLE and lower the BASS. Because the EQ network of BLACK 2x12 lies before the main gain stage of its preamp, pushing the mids results in a lovely, singing blues tone.
Originals tube compliment: 4 x 12AX7s & 2 x 12AT7 (a.k.a. ECC81) in
preamp, 4 x 6L6s in power amp.

3. TWEED 4x10

This 4x10 combo was built in 1959 and originally intended for bass. This said, guitarists were quick to embrace its smooth-yet-cutting on-the- edge tone. TWEED 4x10 is very responsive to both picking strength and guitar volume setting. By backing-off your axes volume when the amp is cranked, you can produce a beautifully clean and full tone. It also means that dynamic picking control allows you to make notes or chords more distorted or clean than others, depending on how hard or how soft you pick.
TONAL NOTE: Just like on the original, the tone controls are highly interactive. The TREBLE, MIDDLE AND BASS controls will affect each other depending on your settings. Originals tube compliment: 1 x 12AY7, 2 x 12AX7s in preamp, 1x GZ34 recti-
er, 2 x 5881s in power amp.

4. AC15

This is modelled on Channel 2 of an amazing sounding 1962 VOX AC15. This 1 x12, 15 Watt, valve driven combo was unleashed on the market in 1958 and was the rst ever VOX amplier. Thanks to its compactness, built in vibrato and tremendous tone, it was a huge hit with the popular British guitar bands of the time. One of the biggest reasons for its signature tone is the fact that it employs EL84 output valves in a Class A circuit with no negative feedback. The result of this design is more perceived power and more distortion the latter of which gets thick with second and third order harmonics that increase as the amp is cranked. Thanks to Valve Reactor Technology the power stage of your amp is automatically switched to its EL84s in a Class A circuit with no feedback emulation whenever AC15 (or AC30TB) is chosen. The AC15 is the very essence of simplicity. The Channel we modelled only has three controls Volume, Brilliance (really a bass cut) and Top Cut. When you select AC15, the GAIN control mimics the originals Volume control. The BASS control acts as the Bass Cut (originally labelled Brilliance) with total variability instead of the original two position switch. Since everyone leaves the Top Cut in the full ON position, weve eliminated this function. So what do the extra TREBLE and MIDDLE controls do? Set them at 12 oclock and theyre neutral (they mimic the tone of the original) or tweak them for extra exibility.

Originals valve compliment: 1 x EF86, 3 x ECC83s, 1 x ECC82 in preamp, 1 x EZ81 rectier, 2 x EL84s in power amp.

5. AC30TB

The rst AC30s were similar to AC15s but with twice the power (using four EL84s) and the addition of a third channel. Just like the AC15, it was instantly popular. Even though it was a runaway success, several artists asked for more tonal exibility. VOX designed an add-on tone circuit using an additional ECC83 valve. The circuit increased gain in the Brilliant channel and added Treble and Bass controls. The AC30s new gutsy tone became an instantly recognisable signature sound of many major groups in the mid 60S. VOX initially called this their Brilliance Unit but it quickly became known as Top Boost. When Top Boost was rst introduced it was only available as a retrot back panel assembly. It was tted to AC30 top panels around 1964. GAIN, TREBLE and BASS mimic the originals Volume, Treble and Bass controls. The MIDDLE is an extra with 12 oclock being its neutral position. Our AC30TB model produces clean sounds that are rich and jangly with a smooth yet detailed top end, and overdrives that have a glorious, throaty bark just like those classic, Class A tones that have made the original a must have in any serious players amp collection.
Originals valve compliment: 5 x ECC83s & 1 x ECC82 in preamp, 1 x GZ34
rectier, 4 x EL84s in power amp.

6. UK 70s

This is based on the High Treble channel of a 1971, 50 Watt, four input, all-valve head. This amp was chosen because the tone was incredibly rich and warm yet biting and distinct! As this amp has no master volume facility, the way to use it to its full potential is to crank the Volume. To achieve the same response as the original, turn the VOLUME to maximum and use the Master Volume to set your desired volume level. Wind the GAIN control all the way up and immerse yourself in an instantly recognizable, organic overdrive that responds beautifully to the subtle dynamics of your playing and dominates classic rock. Rolling back your guitars volume control results in a unique and highly usable clean sound.
Originals valve compliment: 3 x ECC83s in preamp, 2 x EL34s in power amp.

7. UK 80s

This is modelled on a 1983, all tube, single channel 100 Watt head that boasts a Master Volume control a wonderful feature that allows the user to dial in a decent crunch tone without having to max out the amps volume. Invariably played with its Gain control cranked to the max, this amp was responsible for the fat, roaring sound that dominated 80s hard rock and heavy metal. In the 80s this amp was the only amp of choice.and, for many, still is! Although UK 80s became famous for its distinctive, cranium-crushing crunch, it isnt merely a one trick pony and neither is our model just like the original, when you roll back your guitars volume knob youll get a bright, clean sound thats perfect for chord work and will cut through any mix like a hot knife through butter.

EDIT2[TAP+EDIT 1]ATTACK

HINT: In the COMP+PHASER and COMP+CHORUS combination effects, the ATTACK parameter is already set to the optimal value.

PHASER

A model of a much respected and popular analogue phaser, housed in a banana yellow box! TAP SPEED Sets the modulation speed in a range of 0.1.10 [Hz]. EDIT2 SPEED This lets you use the knob to make ne adjustments [TAP+EDIT 1] to the parameter. EDIT3 RESONANCE Adjusts the amount of resonance. [BYPASS+EDIT 1]

CHORUS

This models the rich sound of an analog chorus unit. TAP EDIT2 [TAP+EDIT 1] SPEED SPEED Sets the modulation speed in a range of 0.1.10 [Hz]. This lets you use the knob to make ne adjustments to the parameter.
HINT: In the CHORUS+DELAY combination effect, the SPEED parameter is already set to the optimal value.
EDIT3 MIX [BYPASS+EDIT 1]
Adjusts the mix amount of the effect.

FLANGER

A model of a truly classic anger that unchained a highly inuential modern guitarist who many hail as the godfather of two-handed tapping. TAP SPEED Sets the modulation speed in a range of 0.1.10 [Hz]. EDIT2 SPEED This lets you use the knob to make ne adjustments [TAP+EDIT 1] to the parameter. EDIT3 RESONANCE Adjusts the amount of resonance. [BYPASS+EDIT 1]

TREMOLO

This effect is based on the highly acclaimed tremolo circuit found in a BLACK 2x12. TAP SPEED EDIT2 SPEED [TAP+EDIT 1] EDIT3 DEPTH [BYPASS+EDIT 1] Sets the tremolo speed in a range of 2.5.10 [Hz]. This lets you use the knob to make ne adjustments to the parameter. Adjusts the tremolo depth.

ROTARY

This models a rotary speaker. TAP SPEED Sets the rotational speed of the speaker in a range of 0.8.10 [Hz]. This lets you use the knob to make ne adjustments to the parameter. By adjusting this parameter you can make the rotational speed change automatically in response to the volume of your guitar. If you use this function, set the SPEED to a slow setting.
SPEED EDIT2 [TAP+EDIT 1] EDIT3 SENS [BYPASS+EDIT 1]
This is a model of one of the most respected analogue tape echo machines ever made. In the original the echo is produced by a playback head and the exact delay time is set by varying the motor speed. Many professionals prefer these lo- units because of the warm, dark echoes they produce. TAP TIME EDIT1 MIX EDIT2 TIME [TAP+EDIT 1] EDIT3 FEEDBACK [BYPASS+EDIT 1] Sets the delay time in a range of 1.1486 [ms]. Adjust the mix amount of the delayed sound. This lets you use the knob to make ne adjustments to the parameter. Adjusts the amount of feedback.
HINT: In the CHORUS+DELAY combination effect, the FEEDBACK parameter is already set to the optimal value. WARNING! If you crank up the FEEDBACK too much, an uncontrollable, cascading runaway of echoes will occur. So, use your ears and your common sense when setting this!

4. Theres no sound heard from the LINE/PHONE jack when you use it. Check that the top panel MASTER volume isnt turned all the way down. Make sure sound is coming from the amp. IMPORTANT NOTE: Youll need to unplug your headphones or cable from the LINE/PHONE jack to do this, since plugging something into this jack automatically mutes the amps speakers. If theres still no sound from the amp, go to page 27 Theres no sound coming from the amp. If you do hear sound, check the headphones or cable you are hooking up to this jack.
5. You cant hear any effects. Check that the BYPASS LED isnt lit. If it is lit, the effect is bypassed. Press the BYPASS button to disengage it; the BYPASS LED will go off. Is the EDIT 1 knob turned down too low? Adjust the EDIT 1 knob.

Introduction

WELCOME ABOARD!
hanks for choosing the VOX AD15VT-XL, AD30VT-XL, AD50VT-XL or AD100VT-XL Valvetronix amp. To ensure a long and trouble-free relationship with your new amp, please read this manual carefully, use the amp as directed and keep the manual for future reference.

MAIN FEATURES

The XL-series uses Valve Reactor technology, and feature a power amp circuit containing a 12AX7 (ECC83) dual triode valve (vacuum tube) that would normally be used in a preamp. This allows the amp to produce the true sound and feel of a bona de all valve (tube) amp. Sophisticated modeling technology is used to provide eleven different amps. They range from classic vintage amps of the past to current expensive high-end valve amps, and are accessible at the turn of a knob. Eleven high-quality effects are built in and seven are multi effects that let you use two effects simultaneously plus Noise Reduction. You can store your favorite amp and effect settings as a program, which contain two different settings (CH1 and CH2). You can switch between these settings from the top panel, or by using the optional VFS2 foot switch connected to the rear panel (Channel Select mode). In addition, theres one preset program for each amp type (Preset mode). In Manual mode the sound you hear will reect the physical settings of the knobs. If you connect the optional VFS2 dual foot switch (sold separately), you can use it to switch programs or bypass effects. The power level control (The AD15VT-XL doesnt have this feature.) lets you adjust the output wattage of the power amp. This means that even when the master volume is turned up to the max to drive the Valve Reactor power amp, you can adjust the volume without losing any tone. The external speaker out jack (AD50VT-XL / AD100VT-XL only) lets you connect a guitar speaker cabinet (8 ohm) of your choice. The effect send/return jacks (AD100VT-XL only) allow you to connect your external effect processor in a loop connection.

SWITCHING BETWEEN THE CHANNELS OF A PROGRAM
1. Press the top panel CH (Channel) button. The CH1 or CH2 LED will light, and the program assigned to the corresponding channel will be recalled (Channel Select mode). 2. CH1 and CH2 will alternate each time you press the CH button.
HINT: You can store your favorite settings in each channel of the program. For details, see Storing your program (page 17).

CREATING YOUR OWN SOUNDS

1. Press the top panel MANUAL button. The MANUAL LED will light (youre in Manual mode).
HINT: You can also create your own sounds in Preset mode or Channel Select mode. However, the process is a bit easier to understand in Manual mode, since the positions of all knobs (except the EDIT 1 knob) are exactly what youre hearing. In other words, what you see is what you get!
2. Use the AMP selector to select an amp, and adjust the GAIN, VOLUME, TREBLE, MIDDLE, and BASS accordingly. 3. If you want to use an effect, use the EFFECTS selector to select an effect type, and use the EDIT 1 knob to adjust the depth of the effect. For modulation-type effects like CHORUS or TREMOLO, or the DELAY/REVERB effect, just press the TAP button twice to set the modulation speed or the delay/ reverb time to the corresponding interval it doesnt get much easier than that! If you dont want to use an effect, press the BYPASS button. You can edit more effect parameters but youll have to read the manual to nd out how. 4. When youve come up with a sound you like, write it as described in Storing your program (page 17).
The Guitarists Guided Panel Tour
In this chapter were going to take a look at the top and rear panels of your Valvetronix amp.

A. Top Panel

1. INPUT SECTION
This is where you plug in your guitar.

2. AMP SECTION

Heres where you make your settings. AMP selector switch This selects one of the amp type models. As mentioned earlier, each model replicates the preamp (with its gain and tonal response), the power amp operation (class A or AB), negative feedback circuitry (or lack thereof), and the response of the tone controls and their placement within the circuit. For details, turn to Amp models and effects (page 20). Preset mode (when the PRESET LED is lit) lets you select preset programs that contain typical sound and effect settings for each amp type. GAIN This adjusts the preamp gain. Higher settings will give you more distortion VOLUME This adjusts the volume.

TREBLE, MIDDLE, and BASS This trio of knobs allow you to dial in the exact amount of high, mid, and low frequencies. Also, as youd expect (and hope!), the exact manner in which each one of these controls behaves and also interacts with the others is dependant on the amp model selected. Turn to the Amp models and effects section (page 20) for more information.
NOTE: In keeping with the originals, certain models will produce almost no sound if all of these three tone controls are turned all the way down (counter-clockwise). NOTE: Not all of the original amps that we modeled actually have all three of the Treble, Middle, and Bass controls. In such cases, we allow you to use all three knobs to effectively increase the tonal range of the original. Turn to the Amp models and effects section (page 20) for more information.
MASTER This adjusts the volume that is output from the preamp to the Valve Reactor power amp. This will vary the amount of distortion created by Valve Reactor.
NOTE: The MASTER volume control is NOT programmable. NOTE: The GAIN control also affects the amount of distortion. For some settings, there may be virtually no distortion.

3. EFFECT SECTION

Here you can make settings for effects and noise reduction. For details on each effect, refer to Amp models and effects (page 20). EFFECTS Selects the type of effect. You can use the TAP button, EDIT 1 knob and Bypass button to adjust the parameters of each effect. When you select an effect type, the effect parameters will be initialized and Effect Bypass will be defeated. EDIT 1 Use this to adjust the parameters of each effect. By using this knob in conjunction with the TAP and BYPASS buttons as described below, you can adjust three different parameters. (That is, if the BYPASS LED is dark.) Turn EDIT 1 (without pressing a button) (EDIT 1) Turn EDIT 1 while pressing TAP (EDIT 2) Turn EDIT 1 while pressing BYPASS (EDIT 3) If the BYPASS LED is lit (the effect is bypassed), you can hold down the TAP button and turn the EDIT 1 knob simultaneously to adjust the noise reduction sensitivity.
NOTE: You cant adjust the effect parameters while the BYPASS LED is lit.
TAP (EDIT 2) and LED This button enables you to set the speed of a modulation-type effect (such as CHORUS or FLANGER) the delay time REVERB length; simply press the button twice at the desired interval. The LED blinks at the specied speed or time.
HINT: To set the time to exactly match the tempo of a song, press the TAP button several times along with the song. HINT: You can also adjust the speed or time, by holding down the TAP button and turning the EDIT 1 knob. (This is the EDIT 2 mode) NOTE: If the BYPASS LED is lit, you wont be able to use the TAP switch to set the time. (The TAP LED will be dark.)
BYPASS (EDIT 3) and LED If you dont want to use an effect, press this button to turn the effect off (i.e., bypassed). If the effect is bypassed, this LED will be lit.

NOTE: You cant adjust the effect parameters if the BYPASS LED is lit. HINT: While the effect is bypassed, you can adjust the noise reduction sensitivity by holding down the TAP button and turning the EDIT 1 knob. HINT: The bypass setting is remembered even when you switch modes, switch programs, or turn off the power. HINT: The Bypass button can be used to modify effect parameters (EDIT 3). Press and hold Bypass and simultaneously turn the EDIT 1 knob. See the chart on page 25 for what parameters can be controlled.
4. PRESET/MANUAL/CHANNEL SECTION
PRESET and LED This button puts your Valvetronix amp into Preset mode and you can use the AMP selector to select a typical setting for each amp type. If the PRESET LED is lit, youre in Preset mode! MANUAL and LED This button puts your Valvetronix amp into Manual mode which means the physical position of each knob (except for the EDIT 1 knob) determines exactly what you will hear. This means that the amp will operate just like a conventional guitar amp. If the MANUAL LED is lit, youre in Manual mode. CH (Channel), CH1/CH2 LEDs This button switches between the two channels and The LED of the selected channel will light. In Preset or Manual mode, the CH1 and CH2 LEDs will be dark. If from either of these modes you then press this CH button, youll switch to Channel Select mode, and the channel (1 or 2) that you selected most recently will become active.
WRITE button Use this button to save a new program into CH1 or CH2. Refer to Storing your program (page 17).

5. POWER SWITCH

When the power is on, the indicator located above the switch will be lit.

B. Rear Panel

AD15VT-XL/AD30VT-XL/AD50VT-XL

AD30VT-XL/AD50VT-XL only

AD50VT-XL only

AD100VT-XL

AC power This is where you connect the included power cord. FOOT SW You can connect the optional VFS2 dual foot switch (sold separately) here, and use it to switch programs or bypass the effect while you perform. POWER LEVEL This adjusts the output wattage of the power amp.
AD30VT-XL: less than 0.1 W 30 W AD100VT-XL: less than 0.2 W 100 W NOTE: The AD15VT-XL doesnt have this control. NOTE: The power level setting isnt saved as part of the program. AD50VT-XL: less than 0.15 W 50 W

SELECTING A PRESET PROGRAM
With the PRESET LED lit, turn the AMP selector and the preset program for each amp type will be selected. (The physical settings of the top panel control knobs and EFFECTS selector are ignored at this time.)
HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, the effect is bypassed. Press the BYPASS button once again to cancel bypass and enable the effect once again. The XL-series remembers the bypass setting even if you switch modes or programs, or turn off the power.
CHANNEL SELECT MODE (SELECTING A CHANNEL PROGRAM)
In Channel Select mode you can press the CH button to recall the program saved in each channel (CH1 and CH2), automatically switching all of the amp and effect parameters.
GETTING TO CHANNEL SELECT MODE
If the CH1 and CH2 LEDs are dark, youre not in Channel Select mode. Press the CH button. Either the CH1 or CH2 LED will light, and youll be in Channel Select mode.
NOTE: If the CH1 or CH2 LED is blinking (i.e., when youre in the middle of selecting a writing-destination for the program), the program wont switch when you press the CH button the rst time. In this case, press the TAP button to stop the blinking.

SWITCHING CHANNELS

With either the CH1 or CH2 LED lit, press the CH switch. The channel will change each time you press the button, and the program stored in each channel will be recalled. (The physical settings of the top panel selector knobs and control knobs are ignored at this time.)
HINT: If the optional VFS2 dual foot switch is connected to the rear panel, you can use it to switch programs. For details, refer to Using the VSF2 dual foot switch (page 19). HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the LED. The XL-series remember the bypass setting even if you switch modes or programs, or turn off the power.

MANUAL MODE

When the XL-series is in Manual mode, it works just like a non-programmable guitar amp. In other words, the positions of all top panel selectors and knobs (except for the EDIT 1 knob) indicate exactly what youre hearing.

GETTING TO MANUAL MODE

If the MANUAL LED is dark, youre not in Manual mode. Press the MANUAL button; the MANUAL LED will light, and youll be in Manual mode.

NOTE: If the CH1 or CH2 LED is blinking (i.e., when youre in the middle of selecting a writing-destination for the program), the MANUAL LED wont light when you press the MANUAL button the rst time. In this case, simply press the MANUAL button once again. NOTE: In Manual mode when you edit parameters that arent dened by a knob setting (i.e., effect parameters or noise reduction settings), those settings are saved automatically, and will be recalled the next time you enter Manual mode. However if the EFFECTS selector is at a different position than it was when you were last in Manual mode, the default settings for that effect type will be loaded. HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the LED. The XL-series remembers the bypass setting even if you switch modes, programs, or turn off the power.
Creating and storing your own program
here are two ways you can do this; by tweaking an existing preset program thats close to what you have in mind, or by starting from scratch.
CREATING YOUR OWN PROGRAM
Lets start from scratch. 1. Choose any program in Preset or Channel Select mode, or select Manual mode.
HINT: Since were starting from scratch it doesnt matter what program you choose.
2. Use the BYPASS button to bypass the effect. (The BYPASS LED is lit.) If you want to use an effect, you can add it at the end of this process. 3. Use the AMP selector to select the amp you want to use.
HINT: For details on the amp types, refer to Amp models and effects (page 20).
4. Adjust the top panel GAIN, VOLUME, TREBLE, MIDDLE, and BASS knobs as desired. 5. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise reduction. This setting is also saved as part of your program. For details, refer to Adjusting the noise reduction (page 16)
HINT: Adjust the noise reduction so that you dont hear noise when youre not playing your guitar.
6. If you want to use an effect, press the BYPASS switch once again to turn bypass off (the BYPASS LED goes dark). 7. Select an effect, and make adjustments. For example if you want to add delay, turn the EFFECT selector to DELAY. If the selector is already set to DELAY, youll have to turn it to a different effect and then back to DELAY. Use the TAP button or EDIT 1 knob to adjust the delay time and delay level (the amount of delayed sound). DELAY TIME: DELAY LEVEL: DELAY FEEDBACK: Press the TAP button twice (at the desired interval), or hold down the TAP button and turn EDIT 1. Turn EDIT 1 (without pressing any button). Turn EDIT 1 while holding down the BYPASS button.

HINT: For details on the effects, refer to Amp models and effects (page 20).
8. When youve come up with a sound you like, store the program.
NOTE: In Preset or Channel Select mode, the changes you made will be lost if you switch to a different program or Manual mode or turn off the power without storing the program rst. NOTE: The effect bypass setting isnt stored as part of the program.
ADJUSTING THE NOISE REDUCTION
Heres how to adjust the noise reduction.
NOTE: The noise reduction setting is part of each program. In Preset and Channel Select modes, your setting will be lost if you switch to a different program or to Manual mode (or turn off the power) without storing your edited program rst.
1. Press the BYPASS button to make the BYPASS LED light. 2. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise reduction sensitivity. Turning the knob toward the right will produce greater noise reduction (less noise). If you turn the knob all the way to the left, noise reduction will be off, and wont do anything (more noise).
NOTE: Depending on the guitar youre using, excessively high noise reduction settings may cause notes to be cut off in an unwanted manner!
3. If you want to use effects, press the BYPASS button to make the BYPASS LED go dark and the effect(s) will be heard.

STORING YOUR PROGRAM

When youve come up with a sound you like, you should store (write) the program. 1. Press the WRITE button. The CH1 or CH2 LED will blink. 2. Press the CH button to select the channel in which you want to store your program. The program will be stored in the channel whose indicator is blinking.
HINT: If, during this process, you decide that you really dont want to store the program, you can press the TAP button to cancel at this point. The LED will stop blinking, and youll return to the mode in which you were.
3. Press the WRITE button once again. Your program will be saved in the specied channel, and the LED of the destination channel will stop blinking and remain lit.
NOTE: The program that was previously stored in that channel will be overwritten; in other words, the settings that used to be stored in the channel you selected in step 2 will be erased. NOTE: The effect bypass setting isnt stored as part of the program. NOTE: If youre creating your sound in Preset or Channel Select mode, your changes will disappear if you switch to a different program or to Manual mode before storing.

For this amp type, we modeled the Clean channel of a very rare, very expensive and respected 100 Watt head named the Overdrive Special. We auditioned several top-shelf boutique amps for this model but this amp was the clear winner. Its beautifully rounded low-end, delightfully transient mid-range attack and sweet treble make it the perfect clean sound to complement the high gain destruction that will ensue further down this sound list. Originals tube compliment: 3 x 12AX7s in preamp, 4 x 6L6s in power amp.

FUNKED

This dual channel, black-faced beauty is considered a must- have 2x12 combo for many professionals. Its celebrated clean sound is very tight n twangy, with a deep, taut, piano-like bass. This hot-rodded clean sound was inspired by the glassy clean sounds used by a famous funk metal band. In keeping with the original, when pushed hard the bass tends to crumble so raise the MIDDLE and lower the BASS. Because the EQ network of the FUNKED model lies before the main gain stage of its preamp, pushing the mids results in a singing clean tone. Originals tube compliment: 4 x 12AX7s & 2 x 12AT7 (a.k.a. ECC81) in preamp, 4 x 6L6s in power amp.

BUZZSAW

Fire up the BUZZSAW! This sound was inspired by the pioneering sounds of '70s hard rock and metal. Based on a British-made 50-watt head, this sound churns out a dark, grinding tone perfect for any aspiring prince of darkness! To create this sound, we started with the High Treble channel of a 1971, 50 Watt, four input, allvalve head then we cranked the gain and boosted all bands of the original's EQ. As this amp has no master volume facility, the way to use it to its full potential is to crank the Volume. To achieve the same response as the original, turn the VOLUME to maximum and use the Master Volume to set your desired volume level. Wind the GAIN control all the way up and immerse yourself in an instantly recognizable, organic, driving overdrive. Originals valve compliment: 3 x ECC83s in preamp, 2 x EL34s in power amp.

CRUNCHED

This sound is based on a very rare modded VOX AC30/6TBX Top Boost combo and adds hot-rodded gain levels and a completely twisted EQ to deliver deep, crunchy guitar tones. GAIN, TREBLE and BASS mimic the originals Volume, Treble and Bass controls. The MIDDLE is an extra with 12 oclock being its neutral position. Our CRUNCHED AC30TB model produces rich overdrives that have a glorious, throaty bark -just like those classic, Class A tones that have made the original a must have in any serious players amp collection but taken to a whole new level in the XL range!

Originals valve compliment: 5 x ECC83s & 1 x ECC82 in preamp, 1 x GZ34 rectier, 4 x EL84s in power amp.

THRASHED

This is modeled on a 1983, all tube, single channel 100 Watt head that boasts a Master Volume control - a wonderful feature that allows the user to dial in a great crunch tone without having to max out the amps volume. Invariably played with its Gain control cranked to the max, this amp was responsible for the fat, roaring sound that dominated 80s hard rock and heavy metal. In the 80s this amp was the only amp of choice.and, for many, still is! Although UK 80s amp on which THRASED is based was famous for its distinctive, cranium-crushing crunch, when you roll back your guitars volume knob youll get a bright, clean sound that will cut through any mix like a hot knife through butter. For the XL range, we modded our original UK 80s model adding tons of gain, and scooping the EQ for complete THRASHED destruction! Originals valve compliment: 3 x ECC83s in preamp, 4 x EL34s in power amp.
This sound really needs no introduction! We started with our "UK Modern" model which is modeled on the High Gain channel of a modern, all-tube 100 Watter. It combines a toneful high gain preamp stage with the unmistakable, snarling punch and girth the UK 80s power stage offers. The result is a highly aggressive, tone-breathing monster capable of mondo gain while retaining individual note definition. But that wasn't enough for the XL range. We wanted it to breathe re! So we added some mods to the original sound like boosted bass and mid frequencies, and we--of course--turned up the gain. With the GAIN control on full, RAGED allows lead lines to soar into soulful feedback, while its low-end chunk remains tight and punchy. Wimps beware! Originals valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.

MODERN

This model is an even HIGHER gain modication to the Modern High Gain channel of a brutal, 100 Watt, armour-plated beast. Its deep low-end, somewhat zzy top and Monster-like gain has made this amp a mainstay for many modern, metal acts who either tune their guitars down low, or wield 7 -string axes. We scooped the EQ so much we needed a bulldozer and, yes, we added more gain. Much more. The result is devastating. If you play slamming, nu-metal thats tuned low, then MODERN could well be the only way to go! Originals tube compliment: 5 x 12AX7s in preamp, 2 x 5U4G rectier tubes, 4 x 6L6s in power amp.
If fast, legato licks and thick saturated chunking is your thing, look no further. Again, we started with our "UK Modern" model which is modeled on the High Gain channel of a modern, all-tube 100 Watter. But this time we modded the mid-range EQ to emphasize the almost vocal-like midrange favored by certain legato style players known for using headless guitars and playing VERY fast. Of course, this being the XL range, we dimed out the gain to the absolute max. Plug in and y! Originals valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.

MOLTEN

This is modeled on the Overdrive Channel of an all-tube, 100 Watt head built in 1991 and covered in snakeskin! Last time around, we called this US HIGAIN but our modded MOLTEN sound is capable of even more powerful, heavily saturated sounds that combine an open low-end with compressed mids and highs. The result is a tone that remains focused and well dened at even the most extreme gain settings. Plug in and take cover!
NOTE: The Molten preset features our Octave effect. When the Octave effect is on, we do not recommend playing chords unless you are going for an unusual effect!
Originals tube compliment: 4 x 12AX7s in preamp, 4 x 6L6s in power amp.
This sound was created when we were having some fun mutating our UK Modern model. We wondered what this famous UK-made 100-watt hi-gain amp would sound like if it operated in Class A, rather than Class AB. With this modication, BLACK was born! Like the other XL sounds, it's tailor-made for hi-gain shred, and it's a totally unique sound you can only nd in the XL range! Originals valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.

DAMAGED

For the DAMAGED sound, we started with a US HI GAIN model and then pretty much tossed out the rule book in our quest for gain. Not only did we crank the gain to searing levels, but we completely re-voiced and modied the EQ of the original model. DAMAGED is a thick, dark ultra hi-gain sound. Warn your neighbors and get ready to shred! Originals tube compliment: 4 x 12AX7s in preamp, 4 x 6L6s in power amp.

3. The amp doesnt seem very loud Is your guitar turned up? Is the amps MASTER volume turned down low? (If youre using the AD30VT-XL/AD50VT-XL/AD100VT-XL) Is the POWER LEVEL knob on the rear panel turned down?
Check the settings of the GAIN, VOLUME, TREBLE, MIDDLE, and BASS controls. On certain amp types, if the TREBLE, MIDDLE, and BASS controls are all turned down, there will be little or no sound coming from the amp due to the way the circuit of the original works. If youre in Manual mode (the MANUAL LED lit), turn the following controls above their minimum setting: GAIN, VOLUME, TREBLE, MIDDLE, and BASS.
4. Theres no sound heard from the LINE/PHONE jack when you use it. Check that the top panel MASTER volume isnt turned all the way down. Make sure sound is coming from the amp. IMPORTANT NOTE: Youll need to unplug your headphones or cable from the LINE/PHONE jack to do this, since plugging something into this jack automatically mutes the amps speakers. If theres still no sound from the amp, go to page 29 Theres no sound coming from the amp. If you do hear sound, check the headphones or cable you are hooking up to this jack.
5. You cant hear any effects. Check that the BYPASS LED isnt lit. If it is lit, the effect is bypassed. Press the BYPASS button to disengage it; the BYPASS LED will go off. Is the EDIT 1 knob turned down too low? Adjust the EDIT 1 knob.
