Finally found my Jim Dunlop Crybaby pedal, so here's a couple of pics of the internals:
Here's a tip, if the stock SPDT (single-pole double-throw) footswitch ever goes intermittent in operation, you can easily replace it with a 3PDT footswitch, I did that with my Jimi Hendrix Wah, and after adjusting the footswitch so that the treadle switches it reliably, it worked perfectly.
I'm seriously considering modding both my Jimi Hendrix Wah pedal, and my Crybaby Wah pedal so that they both have indicator leds, I'll start a new thread detailing how to do the indicator led mod later on.
