Crybaby Wah Pedal True Bypass
After seeing the guide from http://homepage.ntlworld.com/s.castledine/greenfuz/tb4.html, I thought it would be a real good idea to do it. My wah pedal sucks out so much of my tone, and after doing the mod, there was a HUGE noticeable difference.
A note before you see the wiring diagram:
The colors of the wiring match the exact ones, you only need to add an addition 3 wires: the RED wire, which goes from the bottom left plug where the green wire connects, to the upper right plug. The green wire from the circuit board to the top middle plug, and then the black wire which connects to the ground on the pot (the ground on the pot is the one where the black wire is connected there)
So here it is:
This is the kind of replacement switch you need. It's a "push on-push off" DPDT switch. I found it on eBay, I haven't found it at RadioShack, so it might take some looking around, but you'll find it.
So, open up the bottom.
Desolder the switch (outlines in green), and remove all the compenents CLEANLY that are circled in red. Be careful not to strip the track on the bottom, I almost did accidently.
Now take a wire, and stick it into the spot the green arrow is pointing to, and solder it down on the bottom as shown in the next picture
You can see it's soldiered in nice and easy.
Solder the other end of the wire to that upper middle lug on the switch.
Then connect up the other wires as are in the wiring diagram. It'll look something like this:
And that's pretty much it! Plus it in and sing away!

A question, in the schematics you wire the blue one to the pot and then from the pot to same blue to the DPDT, in pictures i see the blue wire that is going before in the DPDT and then to the Pot, it's the same thing?

I have a crybaby classic, which came with a dpdt from the factory, but i'd like to install an LED light so i can tell when its on- how would i go about doing that?
