Reverb
Determines the level of the reverb effect from the built in three spring reverb tray. The signal of the reverb
sent to the stereo power stages has been modified so that the reverb is reproduced as a huge ‘surround
sound’ effect.
Master volume
This control sets the main output volume from the preamplifier into the power amplifier. It determines, in
conjunction with the individual channel volume controls, the overall output level of the amplifier. Do not be
afraid to run the amplifier into power stage overdrive - the discrete power amplifier has been designed to
overdrive in a ‘musical’ way and will provide you with significantly more gain and overall volume level. When
being overdriven hard, the Tramp Tube can deliver power levels well in excess of its quoted ‘clean’ output
power.
Master volume boost
Activation of this control is indicated by an LED immediately to the left of the BOOST control. When
activated (the BOOST control defaults to ON), this control determines the amount of extra MASTER volume
control to set up two different levels of the same basic sound, for example when moving from a quiet to
loud passage in a song, or for giving an extra lift in volume for a solo. In addition, if the channel output level
is high, the BOOST function can be used to give more preamplifier overdrive, after all the effects and EQ but
just before the power stage. This function can be remotely switched by plugging a dual footswitch into the
appropriate rear panel socket.
Power on LED
Indicates that power is applied to the unit.
