I have dived into a rabbit hole concerning wahs. I have an Ernie Ball wah that sounds a bit better than stock after some mods, I did a couple mods to my lead guitarist's Joe Bonamassa wah, and my vocalist has a GCB-95 from 1992 that he wants me to spruce up. I decided to get a Sham Wah board after a couple reports from @Guardians of the analog. Here:GotA Clyde McCoy and here:GotA Nebul-Wah Redux.
Barely any of the circuit is intact, I've modded it to the point it can't even be considered a clone of the BBE Ben Wah anymore.
All wired connections are done using dupont quick connectors as I'll be using the same shell for different wah boards. I used a DPDT to be able to select between buffered and unbuffered. The buffer is also changed from a BJT to a JFET, I used the JFET buffer board schematic as an example. I turned the internal Body trim into an external Q control to go from 33K-93K using a B50k potentiometer. I also put a Sweep control as seen on the Jerry Cantrell wah using a B5K potentiometer. My inductor of choice is an Eleca Halo, BC109 for Q2 and Q3, and a Hot Potz II for the wah control. Most hardware is from Love My Switches and the shell is from Synthcube.
Accidently damaged the pad for the tip of the output jack so I had to hardwire it.
Here is the schematic. There really isn't anything of the original circuit left.
