This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Here's the ColorSound Wah-Wah. I hadn't laid out a wah before, probably because I haven't built one myself before, and I don't use one much when I play. Anyway, the ColorSound Wah-Wah is pretty simple and sounds very good. What makes it unique is that it doesn't use an inductor like most wah circuits. This might be a good candidate to throw a buffer in front, but it's not necessary. There is a volume pot which you could omit if you want (in which case the Volume 3 pad becomes the output). You could also throw this in a 1590a if you wanted a non-treadle/fixed wah pedal. Or if you're really brave, you could mod a 1590a into a treadle pedal like Thomas Hafemann did.
