If you're into etching, try etching the GGG moddable wah project. I finished one on a board I bought from somebody and like it quite a bit.
Trove of wah info, Joe Gagan, really likes the Boomerang wah circuit.
You can find PCBs of inductor based wahs on Ebay and you might be able to find pcbs/vero layouts for a Maestro Boomerang
I built the Nurse Quacky layout that Miro did and it's frickin great, works great with a bit of overdrive after it, though it probably is more of a funk thing than rock.
