You'd have better luck posting this in the Guitar Gear & Accessories sub-forum.

All that being said you have a very good amp, but it's a bit too dark/heavy for the more proggy stuff you want to play. I'd personally invest in a Mesa if i wanted a tube amp for that kind of stuff, otherwise I'd go for a multi-effects unit. I also wouldn't consider the les paul too appropriate, but your amp is more of an immediate concern.
