From Jim Marshall
I would personally like to congratulate you on your purchase of this next-generation Marshall MG amplifier.
As a musician myself, I fully understand what it takes to perform live in a band situation. In addition to talent, dedication and a lot of hard work, you also need equipment that does exactly what you ask of it. From the outset, these solid-state amplifiers had to meet the tonal expectations of the modern guitarist whilst also incorporating new and exciting technology. With this goal firmly in mind, I set my experienced R&D team the task of designing a new range of affordable MG amplifiers that would deliver essential modern features together with incredible Marshall tone. Like all the amplifiers in the new MG range, state-of-the-art manufacturing and stringent quality control procedures ensure that these amplifiers meet the high standard of build you have come to expect from all Marshall products.

1. Input Jack Socket

Jack input for your guitar. Use a good quality guitar cable (i.e. one thats screened/shielded) to help prevent noise, interference and unwanted feedback.
2. Volume Control - Clean Channel 3. Channel Switch
This control adjusts the volume of the Clean Channel. This switch allows you to change between the amps two channels, Clean and Overdrive, via the front panel. When the LED is green, the Clean channel is engaged. When the LED is red, the Overdrive channel is engaged.
9. Treble Control (MG15 only)
body to your sound. Attenuating (decreasing) the middle by turning this control anticlockwise will yield a more hollow sound with the bass and treble frequencies appearing to be more accentuated. Conversely, increasing the middle will add body to the sound.
Whether this is your first ever Marshall, or is the latest addition to your arsenal of amps, the tone, flexibility and feel of these compact, rugged units is guaranteed to deliver the goods from bedroom, to backstage, to onstage!
By adjusting the Treble control you can add or take away the higher frequencies in your guitar tone. By increasing the amount of treble you will make your tone brighter, ideal for more percussive playing styles.

10. MP3 Line In Socket

I wish you every success with your new Marshall. Welcome to the family. Yours Sincerely,
4. Gain Control - Overdrive Channel
This control sets the operating level of the pre-amp. Simply turn up the Gain control until the required amount of distortion is achieved.
If you want to jam to your favourite MP3, CD or tape track, merely connect the line out or headphone output of your player here, adjust the volume of your player to match that of your guitar and youve got the perfect play-along practice system.
5. Volume Control - Overdrive Channel 6. Contour Control (MG10 only)
This control adjusts the volume of the Overdrive channel. The louder this channel is set, the looser the amplifier will sound and feel. Dr. Jim Marshall OBE This highly effective tone control works by modifying the mid-range (body). The tone can range from traditional and woody sounding (setting at 10), to balls-to-the-wall (setting at midway), to aggressive, scooped and modern (setting at 0) and all points in-between.
11. Headphones Socket 12. Power Switch
For use when silent practice is the order of the day. Connection of headphones will automatically mute the internal speaker. The power switch turns your amplifier on and off. The Channel switch will light up when your amplifier is turned on and will not be lit when the amplifier is switched off.
7. Bass Control (MG15 only)
* EUROPE ONLY - Note: This equipment has been tested and found to comply with the requirements of the EMC Directive (Environments E1, E2 and E3 EN 55103-1/2) and the Low Voltage Directive in the E.U. * EUROPE ONLY - Note: The Peak Inrush current for the MG10 is 2 amps. The Peak Inrush current for the MG10 is 2.5 amps.
Turning the Bass control will effect the amount of low frequencies or bottom end in your guitar tone. Rotating this clockwise will increase the amount of lower tones creating deeper and thicker sounds. Turning this control anti-clockwise will decrease the bass frequencies in your tone reducing any bottom end thud.

Note: The specific mains input voltage rating that your amplifier has been built for is shown on the back panel. Before connecting to the mains electricity supply, always ensure that your amplifier is compatible with your electricity supply. If you have any doubt, please get advice from a qualified technician. Your Marshall dealer will help you in this respect. Please ensure the amplifier is switched off and unplugged from the mains electricity supply before being moved.

From Jim Marshall

ENGLISH I would like to thank you personally for selecting one of our new 15 Watt, MG combos the MG15CD, the MG15CDR or the MG15DFX. As a musician myself I fully understand the necessity of achieving the right tone and feel to help inspire musicians to reach their full creative potential be they aspiring beginners or more skilled players. With this in mind I set my experienced R&D team the task of designing a new range of affordable MG amplifiers that truly captured the essence of the Marshall sound. Utilising new technologies, some of which were developed for our critically acclaimed AVT range, the new MG Series raises the standard for what can be expected from a value-for-money range of guitar amplifiers and defines a new benchmark. For example, the power amp section of your MG15 combo boasts FDD (Frequency Dependant Damping) a radical new feature that is exclusive to Marshall Amplification and accurately mimics the way an all-valve amplifier interacts with a loudspeaker. As a result of FDD, your new MG15 will give you a sound never before thought possible in such an affordable, non-valve amp. Two of these three units also feature built-in effects the MG15CDR boasts a natural sounding spring reverb, while the MG15DFX houses specially designed Digital Effects (DFX). The DFX featured in the MG15DFX are custom voiced by our own in-house design team. Each one of the four effects on offer (Reverb, Delay, Chorus and Flange) have been designed to give you the true warmth and feel of analogue effects, but in a highly flexible digital format. Furthermore, a wide range of variations for each effect are literally at your fingertips merely tweaking the two digital effects controls on the front panel will give rise to sounds that range from subtle to radical, while always remaining both natural and musical. Like all the amplifiers in my new MG range, the MG15 was completely designed and engineered in the UK and the most rigorous quality control procedures ensure that it meets the standard of build you have come to expect from all Marshall products. Whether the MG15 is your first ever Marshall or is the latest addition to your arsenal of amps, the tone, flexibility and feel of this compact, rugged combo will deliver the goods from bedroom to backstage! I wish you every success with your new Marshall. Welcome to the family Yours Sincerely,

MG15DFX Front Panel Features

1. INPUT jack

Use a good quality (screened) guitar cable to plug your guitar in here.
3. OD (Overdrive) SELECT switch
Depressing the Overdrive Select Switch will engage the Overdrive Channel.

2. Clean VOLUME control

When the OD Select switch is out, this control adjusts the volume of the Clean Channel. At low settings the sound will be very clean with a bell-like ring. Turning this control above half way will introduce a desirable, bluesy distortion as the power amplifier is driven into crunch mode.
4. Overdrive GAIN control
Turning up the Overdrive Gain Control will increase the amount of distortion generated in the Overdrive channel. Low gain settings will produce classic rock and blues tones. Crank the Gain for fat and aggressive sounds that are perfect for soloing or hard rock and nu-metal riffing.

Page 4

5. Overdrive VOLUME control
Amazingly enough, this control adjusts the volume of the Overdrive channel! The louder this channel is set, the looser the amplifier will sound and feel. This behaviour is exactly what a good all-valve amplifier does and is a result of our proprietary FDD circuitry.
11. EMULATED HEADPHONES jack
Plug your headphones here for a killer speaker emulated sound! Doing this mutes your MG15s internal speaker for silent practice.
12. POWER Switch & LED
The power switch turns your amplifier on and off. The LED will be lit when your amplifier is on and will not be lit when the amplifier is switched off. Note: Before connecting to the mains electricity supply, always ensure that your electricity supply is compatible with your amplifier, as detailed on the rear panel. Please ensure the amplifier is switched off and unplugged from the mains electricity supply before being moved.

6. EQ BASS control

This control affects the bass or bottom end of your sound. Increasing the bass control will add warmth to your clean and balls to your overdrive tones.

7. EQ CONTOUR control

This highly effective tone control works by radically modifying the mid-range (body). The tone can range from traditional and woody sounding (setting at 10), to balls-to-the-wall (setting at midway), to aggressive, scooped and modern (setting at 0)and all points inbetween.
13. Reverb LEVEL control (MG15CDR only)
Increasing the Reverb Level control will mix more of the naturally voiced spring reverb signal into your sound as youll find, you can go from subtle to surf at the mere twist of this control!

8. EQ TREBLE control

This control affects the treble or top end of your sound. Increasing the amount of treble will give a glassy edge to your clean sounds and increase the definition on low gain overdrive or the amount of aggressive fizz and cut on high gain tones.
9. FDD (Frequency Dependant Damping) Switch
Marshalls proprietary FDD circuit accurately mimics the way an all-valve amplifier interacts with the loudspeaker and adds a width and depth to your sound which has been unachievable in an affordable solid-state amplifieruntil now!

10. CD IN & EMULATED LINE OUT jack
The MG15s cleverly combine the Line Out and CD Input functions. If you want to jam to your favourite CD or tape, merely connect the headphone output of your CD or tape player here, adjust the CD / TAPE players volume to match that of your guitar and hey-presto youve got the perfect play-along practice system. Alternatively, you can use this socket to connect the MG15 to your multi-track recording machine and youll get a great speaker emulated guitar sound direct to disk or tape. HELPFUL HINT: for silent recording merely plug an unconnected jack plug into the headphone socket and youll disconnect the MG15s internal speaker.

14. Digital FX PRESET / ADJUST control (MG15DFX only)
This control serves a dual purpose. Not only does it allow you to select one of the four types of effects on offer (Reverb (RVB), Delay (DLY), Chorus (CHR) or Flange (FLG)), it also allows you to change a parameter as you sweep it through each of the four effect segments. The parameter you can adjust for each of the four effects is shown below:

Effect

Reverb (RVB)

Parameter (adjustment*)

Reverb Decay Time (from short to long)

Description

A natural sounding Reverb that never sounds harsh or grainy. Short Reverb times produce a plate type effect while longer Reverb times produce much larger sounding hall-type effects. Short Delay Times will automatically have less repeats for groovy surf tones. Increasing the Delay Time automatically increases the number of repeats for a much more atmospheric effect. At slow Speeds a mellow phase-like sweep occurs. As the Speed is increased a more traditional chorus effect is heard. At maximum Speed, a psychedelic vibrato results. At slow Speed settings the amount of regeneration is automatically increased for huge jet engine-like sweeps. As the speed is increased the regeneration decreases to produce a lush, natural sounding flange effect. When the Speed is maxed out, a fast vibrato results.

Delay (DLY)

Delay Time (from short to long)

Chorus (CHR)

Speed (from slow to fast)

Flange (FLG)

*as you turn the control clockwise through the segment dedicated to that effect
15. Digital FX LEVEL control (MG15DFX only)
This controls how much of the chosen effect gets mixed in with your unaffected (dry) guitar tone. Want to hear more of the DFX youve just dialled in? Then simply turn this up!
