From Jim Marshall

ENGLISH I would like to personally thank you for selecting one of two 100 Watt models in my new MG range the MG100DFX 1x12" Combo or the MG100HDFX Head. 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 will help you deliver the goods in each and every playing situation you find yourself in. 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 will deliver the tone youre looking for at all volume levels from quiet late night practice to a full-blown live gig and all points in-between in the way only a Marshall can. Utilising groundbreaking 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 new combo boasts FDD (Frequency Dependent Damping) a radical new feature that is exclusive to Marshall Amplification and accurately mimics the way our all-valve amplifiers interact with a loudspeaker. As a direct result of FDD, your new MG100DFX or MG100HDFX will give you a sound and feel never before thought possible in such an affordable, non-valve amp. The DFX (Digital Effects) featured in both the MG100DFX Combo and MG100HDFX Head have been custom voiced by our in-house digital effects experts. Each one of the five effect types on offer (Chorus/Delay, Delay, Chorus, Flange and Reverb) have been designed to emulate the much sought after warmth and feel of analogue effects, but in a highly flexible digital format. Furthermore, a wide range of variations for each effect are quite literally at your fingertips merely tweaking the three DFX controls (Preset/Adjust & FX Level controls for the Chorus/Delay, Delay, Chorus and Flange options; and a separate Level control for the Reverb) 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 the new MG range, state-of-the-art manufacturing and stringent quality control procedures ensure that these combos meet the high standard of build you have come to expect from all Marshall products. The MG100DFX and MG100HDFX were completely designed and engineered at my Headquarters in Milton Keynes, England. Whether the MG100DFX or MG100HDFX 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! I wish you every success with your new Marshall. Welcome to the family. Yours Sincerely,
E. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as when the power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally or has been dropped. F. NEVER use an amplifier in damp or wet conditions. No objects filled with liquids should be placed on the apparatus. G. ALWAYS unplug this apparatus during lightning storms or if unused for long periods of time. H. PROTECT the power cord from being walked on or pinched particularly at plugs, convenience receptacles and at the point where they exit from the apparatus. I. DO NOT switch the amplifier on without the loudspeaker connected.

MG100DFX & MG100HDFX Front Panel Features

1 1. INPUT jack

Use a good quality guitar cable (i.e. one thats screened/shielded) to plug your guitar in here.
Overdrive Channel. Channel switching can also be done via the included two-way footswitch (when the footswitch is connected the CHANNEL SELECT switch is not functional). Note: When the Overdrive Channel is selected, the OD LED (8) will light up red.
13. Overdrive Channel TREBLE control
This important knob controls the aggressive topend sizzle you have on high gain sounds and the cut and definition of lower gain crunch tones. Experimenting with this control will help you to dial in your own signature tones on your amp.
15. Overdrive Channel VOLUME control
This control adjusts the volume of the Overdrive Channel. The louder you turn up this channel, the looser your amp will sound and feel especially with the FDD switch (21) engaged. This behaviour is exactly what a good all-valve amplifier does and is a result of our proprietary FDD circuitry.
2. Clean Channel GAIN control
The Clean Channel has two selectable modes, Clean & Crunch. When in Clean mode, the Gain control takes you from clean, bell-like tones to a mild, bluesy distortion at high settings. When in Crunch mode, this control takes you from a creamy, 70s crunch, to the roar of a hot-rodded JCM800 and all points in-between.

8. OD LED

When illuminated, this LED indicates that the Overdrive Channel has been selected by either the Channel Select switch (7) or the supplied two-way footswitch.
14. Overdrive Channel CONTOUR control
This highly effective tone control works by radically modifying the mid-range (body) of your sound. The tone can vary from traditional and woody sounding (control set at 0), to balls-to-thewall (control set midway), to aggressive, scooped and modern (turned up to 10) and all points inbetween.
16. Digital FX PRESET / ADJUST control
This control serves a dual purpose. Not only does it allow you to select one of the four types of effects on offer (Chorus / Delay (CHR/DLY), Delay (DLY), Chorus (CHR) or Flange (FLG)), it also allows you to adjust a parameter as you sweep it through each of the four effect segments. The parameter you can adjust for each of the four effect segments is shown below:

3. CLEAN / CRUNCH Select

Push switch to select either clean or crunch sounds on the normal channel (push in for Crunch).
9. Overdrive Channel GAIN control
Turning up the Gain control will increase the amount of preamp distortion generated in the Overdrive Channel. Low Gain control settings will produce classic rock and blues tones. Crank this control for fat and aggressive sounds that are perfect for soloing or hard rock and nu-metal riffing.
4. Clean Channel BASS control
Turning up the Bass control will add warmth and low-end depth to your clean sound. The Bass control can be used in conjunction with the FDD switch (21) to produce deep sounding, valve-like clean tones that are well defined yet still full and round.

Effect

Adjustable Parameter

Description

This multi-effect combines a lush, fixed speed Chorus with a variable time Delay.

10. OD1 / OD2 Select

OD1 mode (switch out) offers more distortion than most amps, OD2 (switch in) takes you to the next level and is definitely not for the faint-hearted!
5. Clean Channel MIDDLE control
Adjusting the middle frequencies in your Clean Channel will vary the amount of 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 Clean Channels sound.
Chorus Delay Time and Delay (from short to long as you turn the (CHR/DLY) Preset/Adjust control clockwise through the CHR/DLY segment) Delay (DLY) Delay Time (from short to long as you turn the Preset/Adjust control clockwise through the DLY segment) Speed (from slow to fast as you turn the Preset/Adjust control clockwise through the CHR segment) Speed (from slow to fast as you turn the Preset/Adjust control clockwise through the FLG segment)

11. Overdrive Channel BASS control
Turning up this control will add extra low-end thump to high gain riffs and a warm, natural sounding depth to lower gain crunch tones. Using the Bass control in conjunction with the FDD switch (21) will allow you to dial in the exact amount of lowend thump and tightness you are looking for.
Short Delay Times will have less repeats for groovy surf and rockabilly tones. Increasing the Delay Time increases the number of repeats for a much more atmospheric, stadium 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 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.

Chorus (CHR)

6. Clean Channel TREBLE control
Increasing the Treble will make your clean sounds brighter and more cutting, turning it down will decrease your tones edge and make it sound softer as a result.
12. Overdrive Channel MIDDLE control
Adjusting the middle frequencies in your Overdrive Channel will vary the amount of 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 Overdrive Channels sound. Flange (FLG)

7. CHANNEL SELECT switch

This push switch allows you to change between the amps two channels, Clean and Overdrive, via the front panel. When this switch is out the Clean Channel is engaged, pushing it in switches to the
17. Digital FX LEVEL control
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 selected? Then simply turn this control up! Important Footswitch Note: Using the supplied two-way footswitch, you can switch the selected DFX on/off.

22. CD IN jack

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 youve got the perfect play-along practice system.
MG100DFX Rear Panel Features
23. EMULATED LINE OUT & HEADPHONES jack
This jack can be used as either an Emulated Line Out or as a Headphone output. This means you can use this socket to connect your amp directly to your multi-track recording machine and youll get a great, speaker emulated guitar sound direct to disk or tape. Alternatively you can plug your headphones in here for a killer, speakeremulated sound! TIP: How to practise or record in silence: The Clean Channel GAIN control (2) and the Overdrive Channel VOLUME control (15) will control the level of the headphone and line out. The speaker output can be adjusted independently using the MASTER VOLUME control (20). Setting the MASTER VOLUME control (20) to zero will allow silent recording or practice.

18. REVERB LEVEL control

This control lets you add a lush Reverb to your sound from a subtle hint to cavernous and all points in-between. Designed by our in-house digital experts, this custom designed Marshall Reverb is highly musical and always sounds natural it never gets harsh or fake sounding. Important Footswitch Note: The supplied footswitch does NOT switch the Reverb on/off.
MG100HDFX Rear Panel Features
19. EFFECTS LOOP MIX control
When using the FX Loop on the rear panel, the FX Mix allows you to dial in the desired amount of effected signal into your overall sound. Turning the control fully clockwise will result in a fully effected sound, i.e. no dry signal and turning the control fully anticlockwise will result in a fully dry sound.
1 1. MAINS INPUT Connector

3. FX RETURN

This is where you connect the OUTPUT of the effects processor you are using in the effects loop.
20. MASTER VOLUME control
As its name suggests, the Master Volume control determines the overall volume of your amplifier. So after setting-up the relative volume of Channels 1 & 2 the overall level can be adjusted without affecting your all-important Clean/Overdrive balance.
24. 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 amplifier is compatible with your electricity supply, as detailed on the rear panel. Please ensure the amplifier is switched off and unplugged from the mains electricity supply before being moved.
The MG amplifier is provided with a detachable mains (power) lead which is connected here. The specific mains input voltage rating that your amplifier requires is clearly indicated on the back panel. Before connecting to the mains for the first time please make sure that your amplifier is compatible with your electricity supply.

4. FX SEND

If you want to use an external effects processor in your amps built-in Parallel effects loop, this is the jack you connect to the INPUT of the unit you are using.
21. FDD (Frequency Dependent Damping) switch

Marshalls proprietary FDD circuit accurately mimics the way an all-valve amplifier interacts with the loudspeaker(s) and adds a width and depth to your sound which has been unachievable in an affordable solid-state amplifier. until now! To engage FDD simply press this switch in.

2. LOUDSPEAKER Output(s)

MG100DFX Combo There is one speaker jack socket on the MG100DFX (marked INTERNAL 4), this is where the MG100DFX power amplifier is connected to the internal Celestion loudspeaker. MG100HDFX Head The MG100HDFX Head has two speaker sockets for connection to either 1 or 2 external cabinets. Ensure the total load impedance is equal to, or exceeds, 4 ohms. Always use a non-screened Marshall approved speaker lead when connecting an extension cabinet to these units.

5. FX LEVEL Switch

Selects the level to match your external effects units (+4dB for rack units and -10dB for pedals).

6. FOOTSWITCH

Connect the supplied two-way footswitch here. Its left button (marked Channel) enables you to change channels and its right button (marked DFX) allows you to switch the DFX Section on/off. Important Footswitch Note: The supplied footswitch does NOT switch the Reverb on/off.
