direct connection to recording or mixing desks.

25. Footswitch Jack 

For connection of the supplied two way footswitch
for channel switching and chorus on/off functions.

8040: 40 Watt COMBO

CHANNEL 1 (Normal)

1. Input Jack 

Connects the guitar to the amplifier.

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 Valvestate
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.

CHANNEL 2 (Boost)

7. Gain Control

Controls the gain level on the boost channel. This
model features an ECC 83/12 AX7 valve in the
pre-amp for incredible overdrive tone and intensity.
Take some time to experiment with the varying
gain levels to find the wide variety of distortion
sounds available.

8. Contour Control

Mid-band contour shift, giving wide voicing sweep
for maximum tonal versatility on overdrive
selections. When used in conjunction with the EQ,
this control is highly effective.

9-10. Bass & Treble Controls 

Interactive EQ controls covering the lower through
to the upper frequencies and offering accurate
sound tailoring.

11. Volume 

Controls the overall volume level of the boost
channel.

MASTER SECTION

12. Master Reverb 

Gives overall control of the depth of reverb effect
for both channels.

13. Pre-amp Output 

Direct output from the combo pre-amp. This gives
a signal suitable for driving an external power amp
or the input of an effects processor.

14. Power Amp In 

Input directly into the combo power amp. This
allows the use of an external pre-amp (eg: 9004),
or acts (in conjunction with pre-amp out) as the
return input from an external effects processor.

15. Line Output 

Filtered output for connection directly to a
recording or PA mixing desk.

16. Footswitch Jack

Socket for the connection of a single footswitch for
normal/ boost channel switching only (model P801
included).

8020: 20 Watt COMBO

CHANNEL 1 (Normal)

1. Input Jack

Connects the guitar to the amplifier.

2. Gain Control 

This controls the level of gain on the normal
channel. The sound remains clean up to half way,
then turns to slight distortion, with full crunch
reached when on maximum gain.

3-4. Treble & Bass 

Controls and adjusts the upper and lower
frequencies of the normal channel.

5. Channel Select 

Push switch to select Normal to Boost channels
(this feature is also footswitchable). This switch
must be in for the footswitch to function.

CHANNEL 2 (Boost)

6. Gain Control 

Control for the gain level of the boost channel.
This takes the sound from bluesy distortion on
lower settings to all out metal on maximum.

7. Contour Control 

Highly effective control which shifts the mid-band
voicing of the boost channel tone. This adds
incredible width and variation to distortion
textures.

8. Presence Control

Adds extra cut and bite to boost selections.
