The Zero Point aims to emulate the comb filter effect we call Flange in the most classic way tonally. The top switch turns the pedal on and the momentary switch below adds that slight flange effect as if you were putting pressure on a secondary tape during playback. Depressing the switch causes the flange to rise, as you let go the flange will automatically start to fall.
The pedal has been tested and functions like it should. Included is the original box.
