range of sonic textures to work with. NOTE: As the VOLTS knob is turned,
the sound may momentarily dip in volume as the signal adjusts to the new
voltage setting.
VOLUME CONTROL – This knob controls the output level of the
DISTORTION side of the pedal. Fully counter-clockwise will produce no
sound. As the VOLUME knob is turned clockwise, the output level will
increase to its maximum volume at the full clockwise setting.
OVERDRIVE SIDE: The OVERDRIVE side can be used independently or
with the DISTORTION side. When both sides are ON, the OVERDRIVE side
follows the DISTORTION side in the signal chain. The overdrive utilizes
two germanium transistors and can go from a nice fattening boost to a
warm overdrive. The overdrive reacts differently to different input levels.
Using hotter pickups, or having the DISTORTION side on will add a variety
of tonal options.
GAIN CONTROL – This knob adjust the amount of gain in the two
germanium transistor preamp gain stage for the OVERDRIVE side. The
gain will increase as the GAIN knob is turned clockwise. Overall, there is
less gain available on this side than the DISTORTION side. The overall
character of the gain will change depending on how the BIAS control is
set.
BIAS CONTROL – This knob adjusts the character of the distortion by
changing the bias of the signal in the preamp section of the overdrive
circuit. When the BIAS knob is at noon, the sound will be the clearest and
most dynamic. When the BIAS knob is fully counter-clockwise, the sound
will be more compressed. When the BIAS knob is fully clockwise, the
sound will start to clip and can add a great vintage grit to the overdrive.
TONE CONTROL – This knob is a single knob tone control. As the TONE
knob is turned clockwise, the tone of the OVERDRIVE side will change
from a low end emphasis to a high end emphasis.
VOLUME CONTROL – This knob controls the output level of the
OVERDRIVE side of the pedal. Fully counter-clockwise will produce no
sound. As the VOLUME knob is turned clockwise, the output level will
increase to its maximum volume at the full clockwise setting.
STATUS LED and FOOTSWITCH (DISTORTION) – When this LED is
lit; the GERMANIUM4 BIG MUFF PI DISTORTION effect is active. When the
LED is off, the DISTORTION side is in True Bypass Mode. The footswitch
engages/disengages this effect. The footswitch controls the true bypass
ON/OFF for the DISTORTION side.
