I have not seen many reports on this circuit, so I thought I would share. This circuit was a lot of fun. I found a non-functional Vox wah to use for the shell. I was going to reclaim the wah pot too, but it was the piece broken in the circuit. The circuit is straight forward, but pay attention to the polarity of the vactrols. The instructions suggest 9 mm or 12 mm pots, but I used one 16 mm pot and think you can use 16 mm for both of them. There was enough room. I did add the LED and would recommend it for all. Lastly, I added a second, outside nut for the power supply. Internally, the power plug is a tight fit next to the vactrols, and this gives it a little more space.
It sounds great, so thanks to @bean!
