Mohs Fuzz

A radically transformed silicon Fuzz Face, the Mohs Fuzz offers a wide range of full fuzz sounds from vintage-flavored to total transistor annihilation.

Named for Friedrich and his scale of mineral hardness, the Mohs features a footswitched “Rhythm” channel (like rolling back your instrument’s volume), “Quartz” (Fuzz Face-y/vintage) and “Diamond” (planet-destroying/modern) modes, and a “Hardness” control for adjusting the character of the fuzz.

The Mohs Fuzz works equally well on guitar and bass instruments.

Controls

I – Input

O – Output

Power jack – 9V DC center negative (standard Boss/Ibanez type) (Mohs Fuzz requires a power supply; it does not have a battery snap)

R – Rhythm channel.  Turn counter-clockwise for cleaner rhythm sounds (this is a pre-fuzz volume control)

SiO2 / C – Quartz/Diamond mode.  Quartz is the standard or default Mohs mode; engage Diamond mode for maximum gain and fuzz.  In Diamond mode at high Hardness levels the Mohs can gate, oscillate, achieve weird and noisy decay artifacts, and do make other unpredictable sounds that vary from unit to unit

H – Hardness.  Softer clipping is found counter-clockwise, harder clipping clockwise

V – Volume

FF – Full Fuzz.  Engaging the FF footswitch removes the Rhythm channel from the circuit

Like a Fuzz Face, the Mohs Fuzz works best when it has an unbuffered connection to your instrument’s pickups (it has a low input impedance).  Placing a buffer in front of the Mohs results in a brighter, harsher sound; experimentation is encouraged.  Unlike a Fuzz Face, Mohs has a low output impedance that can drive a long cable if needed.

The Mohs has enough gain and volume to easily overwhelm a distorted or compressing amp, resulting in a bassy, blown-out sound.  Some combination of moderate output volume on the Mohs (unity or slightly above) and/or using the Rhythm channel at a high level to increase treble response (via higher input impedance) will help match the Mohs to the amp.  Start with the Mohs at unity volume with the bypassed signal, the Rhythm channel all the way up (clockwise), and the FF switch off; slowly turn down the Rhythm channel, slightly increasing the Volume to compensate, until you find your sound.
