Allow JustPedals to introduce the Keeley Moon Op Amp Fuzz Pedal

The Keeley Moon Op Amp Fuzz pedal is a supermassive destroyer, spinning galaxies of gain! Tidal wave bass response gives you tones as heavy as gravity itself. The Moon’s unique filter control offers an expanded range of usable tones, with the filter switch positioned below giving you three distinct EQ phases: “classic” scooped mids, flat EQ, or full range. Feed the Moon Op Amp Fuzz with your favorite drive pedals, and unlock worlds of complex tones!

Quad Op Amp Design

The Moon’s massive sound is achieved with a quad op amp delivering four stages of gain and fuzz. This circuit has its roots in Keeley’s popular Dark Side pedal. In that design, Keeley tailored the tone and gain of the pedal to be a vintage-sounding fuzz optimised for lead work. They wanted to go 180 degrees in the other direction with the Moon pedal’s tone — to achieve infinite-sounding dreamy deep fuzz!

This is a punishingly heavy op amp fuzz designed to extend your guitar or bass frequencies as low as possible. This also means that your lead tones will be extremely harmonically rich. So thick is the fuzz, that your notes will rise and peak into brilliant feedback!

Key Features

  • Based on the fuzz circuit in the popular Keeley Dark Side pedal, but highly tweaked for infinite-sounding dreamy deep fuzz.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.
