The Death By Audio Evil Filter is a psycho HP/BP/LP filter encased in a laser-etched enclosure. It can be driven beyond its limits to produce octave shifts, both up and down, as well as envelope folds. The use of a specific medical-grade IC chip results in an exceptionally precise filter with a unique sound.

The Evil Fuzz feature offers intense sonic destruction, which can be doubled for even more chaos with blooming inverted compression. The CV/Expression input allows for dynamic control of the filter, making it possible to synchronize it with an arpeggiating synth or manipulate it via an expression pedal. It provides an incredible sound experience with synthesizers, guitars, and even amplified skateboards.
