Congratulations on your purchase of the GERMANIUM BIG MUFF
4
PI. The GERMANIUM BIG MUFF PI is a new and versatile
overdrive/distortion that captures the essence of the warm sound
unique to the germanium transistors from the '60s. The
4
GERMANIUM BIG MUFF PI is two independent circuits, one a
distortion and one an overdrive, each with completely independent
controls. The two circuits can be used separately or together. Each
circuit has its own independent ON/OFF bypass footswitch.

-CONTROLS-

DISTORTION SIDE: The DISTORTION side can be used
independently or with the OVERDRIVE side. When both sides are
ON, the DISTORTION side precedes the OVERDRIVE side in the
signal chain. The DISTORTION utilizes two germanium transistors
and is capable of going from clean - to a gritty overdrive - to a full
on distortion and beyond.
GAIN CONTROL – This knob adjusts the amount of preamp gain
for the DISTORTION side of the pedal. As you turn the GAIN knob
clockwise the distortion and volume will increase dramatically.
BIAS CONTROL – This knob adjusts the character of the distortion
by changing the bias of the signal before it is distorted by the
Germanium transistors. Turning the BIAS knob counter-clockwise
will result in a more mellow and compressed tone. Turning the
BIAS knob clockwise will result in an edgy and more aggressive
tone.
