1. Footswitch Jack

Channels on the G30RCD can be switched via
either the front panel or via a footswitch. This
jack is for connection of the footswitch (model
P801).

2. Channel Select Push Switch

For changing channels via the front panel.

3. Input

Plug your guitar in here. We recommend that you
always use a high quality screened cable to help
prevent noise, interference and unwanted
feedback.

4. Volume

This controls the volume of the Clean Channel and
is useful for balancing the level of the Overdrive
and Clean Channels. Once turned past half way
this channel will start to crunch up your guitar
sound for semi-distorted chords and bluesy leads.

5. Bass

Turning this Bass control will affect the amount of
low frequencies or bottom end in your guitar tone

when on the Clean Channel. Rotating this control
clockwise will increase the lower tones and,
depending on other settings, will generally make
your tone warmer. By turning the Bass control
anti-clockwise you will reduce the amount of bass
frequencies in your tone which will make your
sound sharper, thinner and more cutting.

It should be remembered that your guitar will
probably be the main influence in your overall
sound and a naturally bassy guitar for example
will probably need less bass on the amplifier than
a naturally bright guitar.

6. Treble

By adjusting this Treble control you can add or
take away the higher frequencies in your guitar
tone when on the Clean Channel. By turning up
the Treble control and increasing those high
frequencies you will make your guitar sound
brighter and more cutting.

7. Ch.2 On LED

When illuminated this LED indicates that the
Overdrive Channel has been selected.

From Jim Marshall

I would like to thank you personally for selecting
one of our Marshall MG Series guitar combos.
Your new amplifier has been designed by the same
team of British designers who created all of the
great Marshall amps. It is built to the customary
exacting Marshall standards and will give you an
incredible spectrum of sounds to complement a
wide range of playing styles, as well as being
designed to stand the test of time.

The Marshall name has adorned many of Britain’s
finest amps, from the early 1960’s through to the
present day. Some of the original vintage amps
have become highly sought after by both amp
collectors and working guitarists alike.

This new line of transistor guitar and bass guitar
combos have been released to unanimous acclaim.
Your combo is part of a new breed of Marshall
amplifier, which has benefited from years of
experience and continual investment in research and
development.

Not only is the sound quality of your Marshall MG
Series amp of a standard that you would only expect
to come from Marshall’s own design team. The
Marshall G30RCD also has a CD input to allow you
to play along to CD’s. The ultimate home practice
facility.

I would like to wish you every success with your
new Marshall MG Series amplifier, which I am sure
you will find a pleasure to play for years to come.

Yours Sincerely,
