No, never heard of it. But with as much front-end distortion as he's using, it really doesn't matter what kind of amp he's playing into. A solid-state Randall with a Digitech Bad Monkey pedal can sound like that. Lots of harmonics jumping out, but way too much compression, no 'touch' to the distortion.
He's a brilliant player, probably one of the most musical players I've heard in that genre, but I don't much like his sound, and I wouldn't pay to go to one of his concerts. So I'm gonna bow out of this thread, and leave it to people who do enjoy it. He certainly deserves a large audience. :)
