Fuzz. Kosko Series

A classic gritty fuzz featuring a dedicated Bias control for precise tone shaping — from thick and smooth sustain to torn, sputtery, and almost broken textures.
Built around the If 6 Was 9–style circuit, this pedal delivers rich, saturated fuzz with expressive dynamics and old-school character. The Bias control allows you to fine-tune the transistor response, dramatically changing the feel and texture of the distortion — tighten it for focused punch or starve it for gated, fragmented fuzz tones.
Its signature design and full-bodied voice make it a perfect choice for lovers of vintage fuzz, psychedelic rock, and dirty, riff-driven tones.
