Killer

The Killer recreates the Sam Ash Fuzz-Stainer, itself a silicon variation on the Fuzz Face circuit topology. Where germanium Fuzz Faces provide temperature-sensitive, smooth vintage character, silicon transistor Fuzz Faces deliver more consistent, aggressive fuzz tones with increased output and cutting midrange presence. NOS (new old stock) Ukrainian transistors provide the specific tonal character Tom Kogut selected for the circuit, chosen for their gain characteristics and harmonic content.

Level controls overall volume, Fuzz adjusts saturation amount from light grit to full-on fuzz. Tone control sweeps from thin (fully CCW) to thick (fully CW), targeting the frequency range where silicon fuzz interacts with guitar pickups and amplifier input stages. The silicon topology delivers more midrange punch and aggressive attack compared to germanium fuzzes, making the Killer cut through dense band mixes where vintage-style fuzzes often disappear.
