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. Over the

years I have witnessed many advances in amplifier technology and I

wanted this MG series to take full advantage of such innovations.

These solid-state amplifiers had to meet the tonal expectations of the

modern guitarist whilst also incorporating new and exciting digital

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 not only produce the tone you’re looking for, but also offer an

intuitive and totally programmable way of customising, storing and

accessing your favourite Marshall tones and features.
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.
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 on stage!
I wish you every success with your new Marshall. Welcome to the

family...
Yours Sincerely,

Dr. Jim Marshall OBE

1. Input Jack Socket

Jack input for your guitar. Use a good quality guitar

cable (i.e. one that’s screened/shielded) to help prevent

noise, interference and unwanted feedback.
2. Gain Control

Controls the amount of signal entering the pre-amp and

the amount of distortion created in the selected channel.
3. Clean : Crunch Switch

Selects between Clean (green) and Crunch (red) channels.
4. Bass Control

Turning up the Bass control will add warmth and low-

end depth to your sound.
5. OD Switch

Selects between OD1 (green) and OD2 (red) channels.
6. Middle Control

Adjusting the middle frequencies will vary the amount of

body in your sound.
7. Treble Control

Increasing the Treble will make your sounds brighter

and more cutting, turning it down will decrease your

tone’s edge and make it sound softer as a result.
8. Reverb Control

This control lets you add a lush reverb to the selected

channel, from a subtle hint to cavernous and all points

in-between.
9. Volume Control

Controls the volume of the selected channel.
10. Tap (Manual) Switch

Matches the delay FX time to the time between two

pushes. The LED flashes at the selected delay time.

Holding down the Tap switch for longer than 2 seconds

switches the amp between manual and preset mode (pg 2).

When using the optional footcontroller, holding both the

Tap switch and the Store switch will activate the tuner.

11. FX Control

Selects and adjusts one of four effects - Chorus,

Phaser, Flanger & Delay.
12. Store Switch

Stores the current amp settings into the current channel

or into the optional footcontroller. When in manual mode

the Store button lights red.
13. Master Control

Controls the master volume of the amplifier.
14. MP3 Line In Socket

Jam to your favourite MP3, CD or tape track by

connecting the line out or headphone output of your

player here. Adjust the volume of your player to match

that of your guitar and you’ve got the perfect ‘play-

along’ practice system.
15. Footcontroller Socket

¼" Jack socket for the connection of the optional

footcontroller (PEDL-90008) - see page 8.
16. Headphones Socket

For use when silent practice is the order of the day.

Connection of headphones will automatically mute the

internal speaker.
17. Power Switch

The power switch turns your amplifier on and off. A

channel switch will light up when your amplifier is turned

on and none will be lit when the amplifier is switched off.

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.
