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,

8. Gain
This in effect controls the amount of distortion on
the Overdrive Channel. Keeping this control low
will result in crunchy vintage type tones. Turning
this dial up will increase the amount of distortion,
fully clockwise giving maximum distortion
providing a gain drenched tone ideal for heavy
chords, wailing solos and ripping harmonics.
9. Bass
This controls the amount of bottom end or low
frequencies in your guitar tone when on the
Overdrive Channel. When using a heavily
distorted tone, increasing the bass will generally
make the tone darker and heavier.
10. Contour
The Contour control basically shifts the mid-range
frequencies in your guitar tone. By turning the
Contour fully clockwise you will scoop out of your
sound most of the middle frequencies. If you
combine this setting with heavy distortion and
high Treble and Bass settings you can get a killer
thrash tone, perfect for brutal rhythms and nasty
leads. By turning this control fully anti-clockwise
you can get some great fusion type tones. We
would suggest that you spend some time
experimenting with this control to find the
optimum setting for your style, if you’re not sure
simply leave the control set to 12 o’clock.
11. Treble
By adjusting this Treble control you can add or
take away the higher frequencies in your
Overdriven guitar tone. By turning up the Treble
control and increasing those high frequencies you
will give your guitar sound greater cut and more
bite.
12. Volume
This adjusts the overall volume of the Overdrive
Channel, making it possible to balance levels
between the Clean and Overdrive Channels.
13. Reverb
Adding Reverb to your guitar tone will add
ambience and size, giving the effect of playing in a
large empty room or hall.
14. Line Out Jack
The Line Out Jack can be used for direct
connection to recording equipment or for
connection to a P.A.system.
15. Headphone Jack
For use when silent practice is the order of the
day. Connection of headphones will automatically
shut down the internal speaker.
16. CD Input
This is an input for connection to a CD player, tape
player or other auxiliary device, to allow you to
play along. This is a fixed level input, so volume
of your backing music should be adjusted on the
auxiliary unit itself.
17. Power On LED
Indicates operating status of combo. Red
indicates that amp is switched on.
18. Power Switch
Switches the mains power to the combo.
