The Earthquaker Devices Fuzz Master General Octave Fuzz Pedal is a take on the vintage Ace Tone Fuzz Master FM-2 Professional fuzz machine, an octave fuzz very similar to the widely popular Super Fuzz. The basic circuit has been re-imagineered to be more useful for modern players. 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.

A Voice toggle enhances tonal versatility and allows for a variable tone from the classic circuit. The toggle selects between germanium, silicon, and no diode clipping, which significantly impacts fuzz characteristics, upper octave clarity, and output level. Germanium diodes offer more output and an open, looser fuzz tone, while silicon diodes compress the signal and produce a tighter fuzz tone. When set to no diode clipping (center position), the pedal delivers a nearly clean upper octave that borders on ring modulation.

Unlike the original Fuzz Master, which used a foot switch to select between two tone settings, the Fuzz Master General features a variable tone control that enables dialing in anything from a wide open treble assault to a super-scooped, bass-heavy blast. The pedal also provides significantly more output volume and a much lower noise floor than the original vintage unit.

With these enhancements, the Fuzz Master General delivers a more versatile version of the original while retaining the iconic swelling octave grind. Each unit is handmade in mostly tropical Akron, Ohio.
