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

  • Quad Op Amp design delivering 4 stages of gain and fuzz.
  • Based on the fuzz circuit in the popular Keeley Dark Side pedal, but highly tweaked for infinite-sounding dreamy deep fuzz.
  • 3 distinct EQ Modes: Scooped, Flat, Full.
  • True bypass switching.
  • Made in Edmond, USA.
  • Can be powered by a regular 9V DC PSU (centre negative, 2.1 mm, 10 mA current draw).

EQ

While Ed Sheeran primarily relies on the natural sound of his acoustic guitar and vocals, he occasionally uses EQ (Equalization) to shape and enhance his tone during live performances or in the studio. EQ pedals or onboard preamps can allow him to adjust the frequency response of his guitar signal to suit the acoustics of different venues or to achieve specific tonal characteristics. Here’s how EQ might be utilized in Ed Sheeran’s setup:

1. **Tonal Shaping**: EQ can be used to adjust the balance of frequencies in the guitar signal, allowing Ed Sheeran to shape his tone to his liking. For example, he might boost the midrange frequencies to bring out the warmth and presence of his acoustic guitar, or cut certain frequencies to reduce any harshness or mud in the sound.

2. **Feedback Control**: In a live setting, EQ can help control feedback by notching out problematic frequencies that might cause the guitar signal to feed back through the amplification system. This can be particularly useful when performing in venues with challenging acoustics or high volume levels.

3. **Room Correction**: In situations where the venue’s acoustics are less than ideal, EQ can be used to compensate for any deficiencies in the sound. By adjusting the EQ settings, Ed Sheeran can tailor the guitar tone to sound more balanced and natural, regardless of the room’s acoustic properties.

4. **Matching Gear**: EQ can also be used to match the tone of Ed Sheeran’s guitar to the sound of other instruments or equipment in his setup. For example, he might adjust the EQ to complement the tonal characteristics of his vocal microphone or to blend seamlessly with backing tracks or other instruments.

Overall, while EQ may not be a central component of Ed Sheeran’s guitar effects setup, it can still play a valuable role in shaping his tone and ensuring that he achieves the desired sound in different performance environments. Whether used subtly for tonal shaping or more aggressively for feedback control, EQ allows Ed Sheeran to tailor his guitar tone to suit his musical vision and performance needs.

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.
