Hello, I have a wah pedal project. Im want to install an LED on my Crybaby 535Q wah so I know when the wah is engaged. I bought the LED and I plan on buying a new 3PDT to complete my project. On the 3PDT switch, Im not sure how to wire it up. Can anyone help out with a diagram ? I have no trouble taking this thing apart and getting to the +9v and Grnd.
