It’s fuzzy mc-fuzz face. A small little module that offers a unique distortion-type sound. Perfect to put in a rack that’s short on juice and starved for a little mayhem. As a true leech, it draws its current to function from the incoming audio signal so it doesn’t drain your precious voltage lines. You may be certain that you get something unique in your setup. It can be used as a FX type module, or you can use it as a wave-shaper to fatten up those puny sounding oscillators.
