Master of the Fuzz

The Fuzz Master General is EarthQuaker Devices' 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. Their developers have taken the basic circuit and re-imagineered it 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 a full-on buzz-saw assault. EarthQuaker Devices 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 (center position), you can attain a nearly clean upper octave that boarders 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 everyone has come to love. Each Fuzz Master General is made by human hands in mostly tropical Akron, Ohio.


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 tigher, 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 analog octave so single notes work best, but full chords produce an awesome, destructive sound!

EarthQuaker Devices take a standard 9 volt DC power supply with a 2.1mm negative center barrel. The company always recommends 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, therefore, let through unwanted noise. Do not run at higher voltages! Current draw is 10 mA.
