The Fuzz Master General is our take on the vintage Ace Tone Fuzz Master FM-2 Professional fuzz machine, an octave fuzz that was very similar to the wildly popular Super Fuzz. We have taken the basic circuit and re-imagineered it to be more useful for the modern player. The Fuzz Master General features a more accurate Fuzz control that delivers a much broader spectrum of dirt tones ranging from nearly clean through full buzz saw assault. We added a “Voice” toggle to further enhance your dirt desires and wrangle a more variable tone out of the classic circuit. This toggle selects between germanium, silicon and no diode clipping. This has a huge impact on the characteristics of fuzz tone, upper octave clarity and output level. Germanium diodes offer more output and an open, looser fuzz tone, while the silicon diodes compress the signal and yield a tighter fuzz tone. When the voice is set to no diode clipping (centre position) you can attain a nearly clean upper octave that borders on ring modulation! While the original Fuzz Master had a foot switch to select between two different tone settings, the Fuzz Master General has a variable tone control that allows you to dial in anything from a wide-open treble assault to a super-scooped, bass-heavy blast. It also has significantly more output volume and a much lower noise floor than the original, vintage unit. With all these added features, the Fuzz Master General delivers a more versatile version of the original while still retaining the same swelling octave grind we all know and love. Each Fuzz Master General is made by human hands in mostly tropical Akron, Ohio.

Key Features

  • Extremely Limited – We’ve asked and EQD has delivered! The Fuzz Master General is back; however, it is limited to only 1600 units worldwide – so act quickly as these won’t be here long!
  • A Classic Reimagined – Based on the iconic Ace Tone FM-2, the Fuzz Master General has been redesigned from the ground up for modern playing styles and rigs. Its versatile Voice switch lets you easily dial in your perfect Fuzz Octave tone in seconds.
  • Hand Built – The EarthQuacker Devices Fuzz Master General is carefully built in Akron, Ohio, using premium parts to ensure it’s ready for any board, whether on stage, at home or in the studio!

Controls

  • Fuzz: Turning this control clockwise creates more dirt.
  • Tone: Darker and scooped tones clockwise. Brighter and more open tones counter-clockwise
  • Level: Adjusts the output volume.
  • Voice: Three-way toggle switch which selects the clipping style:
    • Mode 1 – Germanium clipping. This produces a more open and looser fuzz.
    • Mode 2 – Silicon clipping. This produces a tighter, more compressed fuzz.
    • Mode 3 – Open, pure transistor drive. This produces a nearly clean octave-up effect and creates a sound very similar to ring modulation.

CAUTION!

Mode 3 is very loud; turn down the level when using this mode. To get the best octave effect, use the neck pickup and play above the 12th fret. This is an analogue octave, so single notes work best, but full chords produce an awesome, destructive sound!

Specifications

  • Dimensions: 4.75″ x 2.50″ x. 2.25″ with knobs
  • Power: 9v – Our pedals take a standard 9-volt DC power supply with a 2.1mm negative centre barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. Do not run at higher voltages!
  • Current Draw: 10 mA.

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.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
