Based on Z.Vex Fuzz Factory
This 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.
Volume – Output level.
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, if you’re that kind. 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. Also use to tune in fat feedback fuzz, if you’re that kind. Lower the Stability and see what happens to this control.
Drive – Increases distortion when used as a “normal” fuzzm and adjusts feedback pitch and tonal thickness, if you’re that kind. 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.
Many ‘incorrect’ settings on this pedal squeal. This may annoy the faint-hearted. If you use the example settings, you won’t get hurt. I don’t want to see anyone hurt. Unless you’re that kind. Don’t forget to memorize or write down your favorite settings.
Hi compression fuzz: Vol 10:00 | Gate 3:00 | Comp 9:00 | Drive 5:00 | Stab 5:00
Velcro fuzz: Vol 10:00 | Gate 7:00 | Comp 5:00 | Drive 5:00 | Stab 2:00
Cleanish hi octave intermodulation: Vol 10:00 | Gate 2-3:00 | Comp 7:00 | Drive 7:00 | Stab 5:00
Smooth fuzz: Vol 10:00 | Gate 7:00 | Comp 3:00 | Drive 5:00 | Stab 5:00 (lower Stab is more mellow)
Radio fuzz: Vol 10:00 | Gate 7:00 | Comp 10:00 | Drive 12:00 | Stab: Lower from fully clockwise while playing open ‘A’ with left hand. Stop at most interesting tone.
