Joe Gore Filth Fuzz. Wild, highly variable fuzz with easy access to the tones you’re likeliest to use. Filth has only got four controls, but it’s a cornucopia of cool, quirky, and usable fuzz flavors.
The drive and level controls do what you’d expect but the real action is in the two sliders. They’re tone controls of a sort, but not in the usual way. Most fuzz tone controls are tone-sucking passive circuits situated downstream from the fuzz effect. But here, the sliders alter the voltages at the transistors, radically changing not only the tone, but also the timbre, response, attack, sustain, and compression. In other words, the sliders radically alter the fuzz’s core character, as opposed to simply EQing a single core tone.
Filth Fuzz was created in San Francisco and is built in Michigan by skilled craftspeople earning a fair wage.
