The Mojo Hand FX 1979 Fuzz is based on the late-’70s Big Muff high-gain distortion and uses op amps instead of transistors. The taper of its Gain pot gives a more-usable sweep, while the second footswitch selects a preset gain that bypasses the Tone control. Mojo Hand pedals are assembled by hand in the U.S. Go to mojohandfx.com.
