Front Panel Functions: What they do and hoW to use them
(5) Gain
This control sets how much signal is sent through the Channel 1 preamp. Low to medium settings will
produce clean sounds. As the control is turned further clockwise the tone will get warmer and eventually
start to add a small amount of overdrive.
(6) treble
This passive control sets the level of the high frequencies for Channel 1.
This will seem more powerful when Over-Boost is switched on due to more high frequencies being
present in the distortion.
(7) mid
This passive control sets the level of the mid range frequencies for Channel 1.
Again it will be more powerful when Over-Boost is switched on.
(8) Bass
This passive control sets the level of the low frequencies for Channel 1.
(9) Volume
This sets the overall level of Channel 1 and is used to balance the sound with the other channels after the
Gain has been set.
(10) reverb
This sets the level of the spring reverb effect on Channel 1.
This is also switchable using the footcontroller.
(11) Presence
This is used to fine tune the high frequency range of the speaker enclosure while on Channel 1, by
varying the damping factor of the tube power stage at high frequencies.
(12) resonance
This is used to fine tune the low frequency range of the speaker enclosure while on Channel 1, by varying
the damping factor of the tube power stage at low frequencies.
