Foot-on-pedal / True Bypass crybaby wah mod

Step 4 Wiring the thing

Ok, soldering time. Use my wiring diagram. It should be clear from that. Don't worry, you will not destroy your wah if you mix up wires.

IMPORTANT:
- Pay attention to the C NO NC symbols on the side of the momentary switch
- pull the wires for the momentary switch through the pot hole, and solder the switch outside the casing. This because you have to install the momentary switch with the wiring already attached to it, and it can't go through the pot hole (learned that the hard way)

This step will keep you busy for a while believe me ;)

Tip: use different colored wires. It makes debugging a LOT easier, since you can track where the wires are coming from.

After you've wired everything, install the momentary switch. Use both hands to screw in the momentary switch (you're turning the switch, not the nut. The nut is locked in place by the rubber). The switch wires now twist into a nice solid string. Be careful not to damage the wiring!

In this diagram, can I withdraw the buffer components or this is not necessary and that will be true bypass even with the buffer there?
Thanks, bro!

I believe the buffer circuit is also bypassed, but i'm not a 100% sure. You can test it by plugging in the wah with out power and turning it on and off. If it really is true bypass, you'll still be able to hear sound coming out of the amp when the wah is turned off.

tank you for the new diagram!!

But i have the same question of Link0126, where goes the blue wire from the harness?

[KoenB]

I can image this being confusing. I'll update the schematic again to make it clear. It should be up in under an hour.

do the two blue wires coming from the wah pot indicate the one wire from the pot as well as the other one coming from the harness? does it matter which one goes on which switch? thanks
