1. Input Jack

Connects the guitar to the amplifier. We
recommend that you always use a high quality
screened cable to help prevent noise, interference
and unwanted feedback.

2. Gain Control

Controls the gain level of the normal channel,
giving clean sounds up to halfway, then bringing
in blues to crunch rhythm sounds as the gain
increases.

3-5. Bass, Middle & Treble

Experimenting with these three wide ranging
interactive bands of equalisation will give you a
clearer understanding of the versatile G50RCD
tones available from this channel.

6. Channel Select Push Switch

Push switch to change from normal to boost
channels. Note - This switch must be in for
footswitch to function.

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 come
to expect from Marshall’s own design team, the
Marshall G50RCD, G80RCD and G100RCD also have
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,
