The Fuzz Master General is EarthQuaker Devices’ modern reimagining of the vintage Ace Tone Fuzz Master FM-2, delivering all the chaotic octave fuzz tones of the original—with vastly expanded versatility for today’s players.

At its core, it’s a ferocious fuzz machine capable of everything from vintage Super Fuzz textures to nearly clean octave-up tones bordering on ring modulation. A three-way Voice toggle lets you shape the clipping style: warm and loose Germanium, tight and compressed Silicon, or Open for raw transistor drive. Pair that with an enhanced Fuzz control and a wide-range Tone knob, and you’ve got fuzz tones from treble-sharp to bass-heavy blasts—all with improved output and reduced noise.

Whether you’re chasing searing leads, destructive chords, or analog octave madness, the Fuzz Master General commands the battlefield.
