Contour Pot

Contour Pot is a potentiometer-sized passive audio filter for adding to existing (or new) footpedals, stompboxes, preamps, etc., for more tonal flexibility. (DO NOT CONNECT TO AMPLIFIER OUTPUTS OR SPEAKER OUTPUTS!).

Connection is simple: run the line-level audio input to the IN and line-level audio output OUT back to your audio circuit. Also requires a Ground GND.

No voltages as necessary, as it is a passive filter circuit.
