STANDBY:
This input is attenuated down approximately 6dB from the high input. It is useful in obtaining
output that is "tight" not "mushy" from high gain humbucker type pickups.
Adjusts the overall volume of the clean channel
Adds brightness and sparkle to the upper frequencies of the clean and clean drive
channel
This pot controls the amount of 'Valve" drive applied to the circuit.
Sets the overall volume level of the clean channel drive sound.
Engages the clean channel drive sound (Also footswitchable)
Controls the low frequency EQ in the pre amplifier.
Controls the mid frequency EQ in the pre amplifier.
Controls the high frequency EQ in the pre amplifier
Controls the level of reverb assigned to each channel
Controls the signal level upon its return from an external processor and blends it to the desired
level with the main signal.
Selects the required channel which is displayed by an illuminated indicator. The upper
channel produces the clean tone and mild overdrive that is reminiscent of a sixties American valve combo. The
lower channel produces the more substantial overdrive and distortion that is associated with British valve
stacks.
Adjusts the 'damping' control of the amplifier speaker enclosure, thereby controlling the
'tightness' of the bass responce. This effect is very cabinet dependant so the switch should be adjusted to taste.
This switch enables/disengages the high voltage DC to the valves, switching the amplifier from a
'wait state' to an 'active state'. The AC voltage to the heaters is not effected by this switch so that an instant on
of the amplifier is achieved when switching to an active state, so long as the POWER SWITCH has remained in
the ON position. Always switch the amplifier to the 'STANDBY' before turning the main power switch off.
This will prolong valve life
