This product was a customer return but is in great condition.

Psycho HP/BP/LP filter with a laser etched enclosure. Can be pushed past the limit to glitch out into octaves up, down, and envelope folds. The specific medical grade IC chip used allows for a hyper precise filter that sounds like no other. The Evil Fuzz is just that totally psychotic destruction or totally psychotic destruction times two with blooming inverted compression. The CV/Expression in enables you to move the filter up and down in sync with an arpeggiating synth or control it with an expression pedal
