Im pretty sure he uses an MXR Distortion + for most of his distorted riffs. And, if you really want to sound like him im pretty sure they have a signature guitar our there for him. Also; sometimes it sounds like he uses a wah pedal that is set on the "sweet spot" (right in between the up and down positions. try and get the pedal strait across and parallell to the floor). It sounds like th wah thing in Crazy Train.

Good luck to ya!
