Preamp Section:
PREAMP- The Preamp section sets up your input gain and basic clean tone.
INPUT JACK- High Impedance input will not load pickups and is extremely pedal friendly.
VOLUME- Sets the input Volume strength (or Signal Gain) and is active for both Clean and Overdrive
channels.
Note: If set too low you may not have a pleasing OD sound. If set too high your cleans might not be
clean enough.
Generally set for the "sweet spot" which is noon to 2 O'clock
Strat's and other guitars with single coil pickups tend to favor a higher setting.
That said breaking rules is ok too. One can use this control to push the clean channel into some tones
reminiscent of small powered tweed amps pushed over the edge. Pull to engage a brighter tone.
TREBLE- Sets level of higher band frequencies. Pull to engage a lower gain "Jazz" mode.
Note that jazz mode is effectively defeated when using the preamp boost.
MIDDLE- Sets level of middle band frequencies. Pull to engage a mid boost.
BASS- Sets the level of low band frequencies. Turn this control all the way "OFF" (till it clicks) to engage
the Preamp Boost.
This feature can also be engaged via the Preamp Boost button on the footswitch.
Overdrive Section:
