giving clean sounds up to halfway, then bringing

in blues to crunch rhythm sounds as the gain

increases.

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

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,
