The Evil Filter, from Death By Audio, is a psycho HP/BP/LP filter with a laser etched enclosure. It can be pushed past the limit to glitch out into octaves up, down, and envelope folds. The Evil Fuzz is just that total balls to the wall or balls to the wall times 2 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. It sounds amazing with synth, guitar, and amplified skateboard.
