The Keeley Moon Fuzz is the first new fuzz release of the Oklahoma-based builder in years, and it’s a variant on the fuzz circuit included in their popular Dark Side multi-effect.

This is a rather simple, 3-knob + 1-toggle quad op-amp Muff-style fuzz with a massive tone due to the fact that its four stages of gain and fuzz don’t lose any low end.

It features a filter section that lets you pick among three filter shapes through the toggle switch in the middle of the case: Flat, Full, and Scooped.

The emphasis of this pedal is all in delivering extremely thick, deep, “punishingly heavy” fuzz “designed to extend your guitar or bass frequencies as low as possible.”

See if it keeps this promise in the videos below.

Keeley Moon Fuzz, Builder’s Notes

The Moon Op Amp Fuzz is a supermassive destroyer, spinning galaxies of gain. Tidal wave bass response gives you tones heavy as gravity itself.

The filter control offers an expanded range of usable tones and the filter switch gives you three distinct EQ phases: Scooped Mids ‘classic’, Flat EQ, or Full Range.

Feed the Moon Op Amp Fuzz with your favorite drive pedals and unlock worlds of complex tones.
