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. Sounds amazing with synth, guitar, and amplified skateboard.
