I wanted to post some wah circuits that I found.
Wah circuit #1
This first one is from a great page that tells you everything you ever wanted to know about WAH PEDALS.

Wah circuit #2
This next one is from diyguitarist.com
I found the article here:
Wah circuit #3
This one just looked really simple. I think you can even buy the kit from the page.

That’s just a few of the many that I found. Again, I really like the first link because the page really goes into what it takes to get that classic wah wah sound. Including, where to get the 500mH inductor. (hint: it’s actually a audio transformer from Radio Shack… well half of it anyway)
I hope this helps somebody out.
