Blue Colander Tibetan Quaalude

Sunn Model-T style distortion pedal with selected JFET transistors vor maximum overdrive.

CONTROLS:

Please see block diagram document representing internal stages sequence to better understand pedal operation. Each stage of pedal’s circuit provides different harmonic content, so distorting any of them yields in a different overall sound.

– boost sets dirty booster output level
– normal/brite knobs set channels output level
– bass/midrange/treble – interactive EQ
– volume sets total preamp output level (in front of output stage), the same operation as ‘master volume’ knob in Model T amplifier
– master – true master volume control (at the very end of Quaalude’s circuitry).

BE CAREFUL with tweaking volume and master knobs – pedal can get deafening loud. Best setting to start is master maxed, volume, normal and brite at 9 o’clock. Turn channels to taste and eventually alter master to volume relation.

INTERNAL CONTROLS:
– high gain boost switch – down position for moderately dirty boost, up position for very dirty boost
– ultra lo switch – down position for original Model T voicing (lowest bass range is attenuated), up position for boosted lows (lowest bass range is flat)
– boost mode selector – separate mode for standalone use, slave mode for ‘channel’ operation activated when ‘standby’ footswitch is on
