TRUE BYPASS FOR STOMPBOXES OR PEDALS!!! - Part 2 of 2

This is the schematic of a true bypass. You can see you need a triple pole double throw switch (3PDT). The click-free thing is to put the input of the FX on ground while playing clean. The output doesn't matter. To avoid blowing up your opamps by accidently swap (+)/(-), you can put a 1N4001 diode over the DC current input. The capacitor of 100uF buffers the DC nicely. But anyone knows to put stabilized voltage on pedals to avoid annoying hum (50 Hz noise) on your output. The short leg of the diode is the cathode. Music sample: www.panicindetroit.nu Panic in Detroit
