Wah Pedal Wiring Diagram. It s the same pcb you can see here the pcb back is labeled 1967 c peterson a serial number. Note that not all of these schematics are guaranteed to work.
This diagram is is a slight variation on others you may find because it has been wired 50s stylein a nutshell the capacitor is wired so that highs are maintained when volume is rolled off. In this case ive used the boss pedal width of 287 inches dividing into the 24 inches of the pedalboard. Polarity refers to the wiring configuration of an expression pedal and the wiring.
But they do differ somewhat.

The stock wah pedal has been around since at least the early 60s. I have added notes in red to the schematics believed to have errorsitems confirmed by me or others have an ok. This is not meant to discourage.
