Envelope Filter with Fuzz

West Co's first signature pedal inspired by one of the world's funkiest drummers, Curt Bisquera. Buffer-Splitter-Fuzz-Envelope Filter. A unique pedal that has the fuzz in front of the envelope filter. If you like your funk a little nasty, this is for you. Can also be used as an envelope filter only. The detector and audio circuits are specifically tweaked for bass (green knob and LED version) or guitar (orange knob and LED version).
