I have a Dunlop CryBaby wah pedal, and when I play it on a clean channel, it sounds fine, but when I play it with distortion, it sounds awful, like a nasly sound being fed through a tin can. All Im using is the wah and a ProCo Rat II, and no matter how I tweak my amp, pedal, or the settings on my guitar, it always sounds horrible, and I only use mild distortion I have my setup going amp-wah-rat-guitar.

Get off this damn forum and play your damn guitar.

Yeah, switch where the rat and wah are in the chain. So instead of going amp-wah-rat-guitar, go amp-rat-wah-guitar. Thats the way most people run it, and for good reason.
