CHANNEL 1 (Normal)

1. Input Jack

Connects the guitar to the amplifier.

2. Gain Control 

Controls the gain level of the normal channel on
both Clean and Crunch selections. In Clean mode,
sounds remain clean, even at high gain levels.
When switched to Crunch mode the amount of
crunch increases as you wind the gain up.

3. Clean/Crunch Rhythm Switch

Push switch to select either clean or crunch sounds
on the normal channel (push in for Crunch).

4-6. Bass, Middle & Treble

Full 3 band EQ for normal channel tonal
selections. These controls are effective and
interactive to give you incredible versatility. Try as
many combinations as possible to really get to
know your EQ.

7. Channel Select 

Normal to boost channel selector switch. This
function is also footswitchable. Set the switch to
the in position for the footswitch to function.
LED’s indicate which mode has been selected.

CHANNEL 2 (Boost)

8. Gain Control

Controls the gain level of the boost channel, which
features  ECC 83/12 AX7 valve drive. This control
is effective on either overdrive selection. On OD1,
it fattens the bluesy distortion and on OD2 goes
from rock overdrive to full metallic thrash as you
turn it up.

9. Overdrive Select (OD1 to OD2)

Manually switches from creamy “classic” OD1 to
screaming “Hi Gain” OD2 distortion modes.

10-12. Bass, Middle & Treble 

Effective 3 band EQ to shape the tone of all
overdrive selections.

13. Contour Control

This sweeping control shifts the mid-band voicing
of the boost channel to give amazing versatility to
your overdrive sounds. When used in conjunction
with the 3 band EQ, this control is devastating!

14. Volume Control 

Controlling the overall level of the boost channel,
this allows volume balancing between the two
channels.

MASTER SECTION
(8080 & 8100)

15. Effects Send Jack

For linking to the input of an external effects
processor.

16. Effects Level Switch 

Selects the level to match your external effects

units (0dB for rack units and -20dB for pedals).

17. Effects Return Jack

For connection from the output of an external
effects processor.

18. Effects Mix  

Allows you to mix the effects to dry signal. Note, if
no effects pocsessor in line, Effects Mix fully
clockwise will result in no signal. 

19. Master Reverb 

Controls the level of reverb effect on all channel
selections.

20. Master Volume 

Controls the overall volume level of the amp or
combo.

21. Line Out Jack 

Filtered low level signal for linking to a recording
or mixing desk.

22. Footswitch Jack

For the connection of a two way footswitch for
reverb and channel selection (Marshall footswitch
P802 included).

MASTER SECTION (8240)

The 8240 has identical features up to item 17, then
as follows.

17. Effects Returns 

Jacks for connection from the left and right outputs 
of an external stereo effects processor (left return 
also acts as the return for a mono effects processor
if used).
