The Fuzz Master General is Earthquaker's take on the vintage Ace Tone Fuzz Master FM-2 Professional fuzz machine, an octave fuzz that was very similar to the popular Super Fuzz.
They have taken the basic circuit and re-imagined 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. A Voice toggle was added 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 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 everything in between a wide-open treble assault and a super-scooped, bass-heavy 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.
