Keeley Psi Fuzz Hybrid Germanium Fuzz Pedal - Used

The Keeley Psi Fuzz is a distinctive hybrid fuzz pedal from Keeley Electronics, blending op-amp and germanium transistor stages to create a wide range of expressive, character-rich fuzz tones. Designed as a modern take on vintage fuzz circuits, the Psi Fuzz delivers everything from smooth, creamy sustain to more aggressive, gnarly textures with strong midrange presence and a tight low end.

With a simple and intuitive control layout, the Psi Fuzz is easy to dial in while remaining highly responsive to playing dynamics. It cleans up well with changes to your guitar’s volume and reacts naturally to pick attack, making it a versatile fuzz for players who want something a little different from traditional Big Muff-style designs. Built in the USA, it reflects Keeley’s reputation for boutique-grade tone and robust construction.
