From the post
Based on Analogguru's schematic, I really don't know much about this other than it's supposed to be a cocked wah effect but it was a request and looks like something a bit different. At least it's a bit of a detour from the usual dirt pedals! :o)
I couldn't find many demos out there either but here is one I found on Youtube:
