The basic function is an envelope filter for modern players. Based on the classic design, it has deep filtering and external expression pedal control. To make it even more exciting, the pedal adds crazy -1, +1, +2 octave analog gate fuzz. You’ll get amazing synth sounds you’ve never heard before. These two effects are turned on and off independently by two foot switches, so you can specify them individually or in a mix. A crazy effects pedal for guitars, basses, and synthesizers.
