I'm looking to buy a wah, and I was wondering what the general opinion was.

I tried the BOSS GT-3, and the wah was alright, but not very customizable (all the wah effects using the pedal sounded pretty much alike).

I read in a book teaching you how to play the wah that the Dunlop Crybaby was the exact same as the Vox wah. Mind you, this book was written by Dunlop, for the Crybaby wah.

Are there any other wahs out there that haven't been mentioned (i haven't forgotten about the bad horsie). Also, what should I look for in a wah pedal?
