Wait till they have the Vox V847 instock and try that one,I think you'll like it.
I have one and it has a much more wider sweep than a standard crybaby.And it seeems athat the more amp gain you use the more noticable the wah sound gets.This after all the same wah-wah Clapton,Hendrix,Page and tons of others use.
The Clyde McCoy is sposed to be like a muted trumphet sound not a normal wah.And as afr as my ears have told me The V847 has kicked all the crybaby type wahs I've ever played through.
Another one that is spossed to be good is the Boss wah with all the fanc modes etc...I heard it on a promo CD and it sounded nice.
