Big, bold, smooth sustain and greater tonal versatility.

When Keeley Engineering began designing the Psi Fuzz, they wanted to take a classic design with lots of history and make it obviously something new. In the case of the Psi Fuzz, they took the op-amp version of the old PI and inverted one of the stages, brought out the midrange, tightened the bass, and most importantly, added a Germanium transistor output. Use of modern quad op amps with a custom germanium output stage provides even higher gain while maintaining vintage warmth, while the custom tone control is tuned for incredible musical flexibility. The Psi Fuzz features a single, integrated circuit package, a quad op-amp, and a single transistor, all of which help make it trim and slick.

On top of it's tonal abilities, it comes with a custom art design in a late 1960s style hand drawn by Erin Lofties. Her stunning artwork looks out of the '60s and was completed this week specifically for this pedal.
