Transistor Fuzz Pedal
FUZZ is a modified and corrected version of the classic two-transistor Fuzz-Face (Tone Bender Mk1) with a buffered TONE control added. Although the legendary circuit was brilliantly simple and sounds wonderful, it has a few drawbacks; notably low input impedance, sensitivity to transistor gain and temperature. Over the years people have attempted various improvements such as transistor sorting and adjustable bias, but these are band-aids and only go so far. FUZZ tackles both problems with fundamental circuit modifications, improving low-level linearity, bias stability, and increasing input impedance by a factor of ten. You no longer have to put this pedal first in the chain, as most pedals will be able to drive it! The warm, asymmetrical clipping and range of tones of the original are preserved.
