From the post
Well as promised I've taken the and made layouts for 7 of some of the most desirable vintage wahs. You'll notice that they all look damn near identical, and that's because they're all based on the same circuit with some component differences. So instead of doing my usual description for each, I figured I'll let the videos speak for themselves.
Original Thomas Organ CryBaby
Vox Grey Wah
Vox v847
Shin Ei Wah
Maestro Boomerang BG-1
Maestro Boomerang Wah BG-2
One note about the BG-2 that makes it different from all the others. The switch allows it to go from a wah to a volume pedal.
Colorsound Wah-Wah
