Mike, how the heck do you know that? You get to eyeball one? which wah? all of them?
tried looking up the vintage schem for the morley, but truthfully don't know which one he used. the colorsound and thomas organ/vox/mccoy wah's didn't have an input buffer stage in the circuit. those came in the 90's iirc. in my experiments with both a modern dunlop crybaby and a modded version/input buffer eliminated. the optimal spot in the chain is in the effects loop when using an opamp preamp. a photo of jerry with tiger and the older rack and setup, over at ruk's photo page, shows what appears to be a thomas organ wah wired into a loop, bottom shelf, in his JC effects switcher. there are other photo's showing the same thing. it's also printed in a book as being on the floor unit for the switcher. before the effects loop, was also before the opamp buffer. so the preamp is a blaster and the guitar to amp was a simple, standard chain.

71-mid 74 (at least to 5/25/74): ColorSound
Oct. 74: possibly a Thomas Organ
75-95: no idea.
all the wahs are verified you stated. and i will defer to you on the dates. parish states that he did in fact use a vox at one time also. didn't the wah fade out when the 90's rack came along, or possibly a little before?
