The unique sounding Fuzz Factory is a five-knob fuzz using two new old-stock sixties germanium transistors. The circuit is not modeled after any classic fuzz design, but should have been around when Leary was still lucid. Although the five knobs are named for the parameters over which they seem to have the most control, please don’t hold me to it. They are controls for various operating levels and biases, and basically shape you a personalized fuzz.
ZVEX Vexter Fuzz Factory Controls
Output level: Volume
Gate: Squelches noise after end of sustain. Turn to right to eliminate squeals, hiss and buzz, stopping just as they disappear, or use to tune in exact feedback pitch. Turning to left opens gate.
Compress: Adds attack characteristic when turned to left, which gets softer to right, and suddenly pinches tone when all the way right.
Drive: Increases distortion when used as a “normal” fuzz and adjusts feedback pitch and tonal thickness. This control becomes meaningless when Compress is all the way right
Stab: use all the way right. Do not adjust this control below 2:00, unless you like your fuzz soft and squishy. Use to control feedback pitch
