This is where you plug your guitar into the
amp. You must use a screened (shielded)
guitar cable. Never use an unscreened
(unshielded) speaker cable. The input to any
guitar amplifier is a very sensitive part of the
signal path and is therefore susceptible to
airborne radio interference, hence the need for
a screened guitar cable. This screened cable
should preferably be of good quality. If you are
in any doubt regarding this, your Marshall
dealer will be more than happy to help and
advise you.

This control sets the overall output volume of
the amplifier.
TToonnaall ttiipp::
It is practical to set this first to suit
the environment in which you are playing as
the position of the volume largely dictates the
optimum positions for the other controls.

This control determines the amount of high
frequency that is present and gives your guitar
tone a defining edge as it is turned up.
44.. MMiiddddllee
This controls the mid-range of your sound.
Turning this up will make your guitar sound
fatter and fuller.
55.. BBaassss
This controls the amount of low frequencies
(bottom end) in your tone.
66.. MMaaiinnss IInnddiiccaattoorr
This red indicator will light up whenever the
amp is plugged into the mains and the Power
Switch (7) is on.
NNoottee::
Please allow a minute or so for the amp
to ‘warm up’ after switching on. This is
perfectly normal with valves as they need to
come up to their ‘working temperature’.
77.. PPoowweerr SSwwiittcchh
This is the On/Off switch for the mains electric
power to the amplifier.
NNoottee::
Please ensure the amplifier is switched
off and unplugged from the mains electricity
supply whenever it is moved!
