I like that little Peavey quite a bit. Before I got the "tube tamer" the tubes rattled horribly, but now not at all. It has a nice warm tone and breaks up pretty nicely when you overdrive it. What I don't like about it there's no way to bypass on it and go directly into an interface for recording. The newer(?) models have that capability.
I've used a Blues Deluxe before and really like that amp too... probably a little more than mine.
I actually like to use that amp without any pedals or effects with my Heritage. It has a nice warm, woody tone just straight through. I do also play my G&L through the Rat and it works pretty well for that, but not like some rigs.
I also have a Marshall Valvestate 100 that is OK, but I just use it as a backup.
