hi averyone i have heard that if you add a dpdt switch(a normal one) you can switch between wah and volumen pedal, the dpdt just switches a 4,7uf tha just turns off the wah pedal, its that true?? and if its so, where does it have tobe connected??

It is true indeed, although I don't know if you can mute your signal completely...

I don't know if the cap has to be lift off or shorted, but remove the 4µ7 capacitor (check polrity), and experiment to check if the wah "volumes" when it's shorted or open.

Then adapt the switch accordingly. A unipolar (SPxT?) switch would be enough I guess...
- Are you a mod or a rocker?
- Uh, no, I'm a mocker.

for example if i wire the positive lug of the cap on the NC and wire the negative lug to C, also i have to wire the C lug to the negative side in the PCB, an the NC goes to the positive of the PCB??? i nor really sure how to wire the cap with the switch on the image(SPDT)
