I never did find a real genuine wah that wanted to play nice with my Tiger guitar ... tried a Vox, a Clyde, older CryBaby ... always sounded too thin.
Wound up using an old Roland digital guitar preamp I had, a GP-100, that has a wah onboard ... ran an expression pedal back to the rack via the Ground Control and used only the wah on there. Worked okay. I still have it, it was top of the line in the early 90s with its COSM modeling, and sold for a grand or so. I put it on ebay every so often for $300 and no one ever buys it ... LOL ... has some other nice effects on it, Roland's Slow Gear which is pretty cool.
It was always available as a backup if my real preamp had gone down, but I never had to use it that way. Nice little piece.
