Built around an all-analog audio path, this dual-band envelope filter combines an articulate attack generator with an expanded set of controls for shaping classic funk sweeps, vocal filter movement, and more restrained fixed-filter textures. Its response follows playing dynamics closely, allowing pick attack and instrument output to drive the filter naturally.

The Color control blends a second parallel low-pass filter into the primary response. This adds girth and growl while smoothing aggressive high-frequency peaks, moving the sound from a familiar single-filter sweep toward a thicker, throatier voice.

Depth, Frequency, and Sensitivity controls tune the envelope response, center frequency, opening speed, and hold behavior. Turning Sensitivity fully counterclockwise lets the pedal operate as a fixed filter. The Direction switch selects forward or reverse sweeps, and the Output control sets the overall level.
