The Corruptor is both a brutal sounding CMOS-based ring modulator and a glitchy fuzz. It turns your guitarsignal into a squarewave and modulates it against an internal oscillator to produce extreme sounds. The ring modulated sound can be blended with straight square wave fuzz.
The new 3.0 can accepts a CV input to modulate the carrier frequency, to produce really insane sounds.
