I have to admit, I really like the 2555 and 2550 Marshall Jubilees and Slash model. If you bias them nicely with the best tubes, they kick butt. Everything from Voxy cleans to Zakk Wylde type gain....you can dial in a lot of shades of gain with it.
When I compare it to the Bogner Ecstasy, the Jubilee has more 80's JCM800 modded crunch, but the Bogner stomps on it, since it's wider sounding, and has throaty growly mids, almost like a 72 Marshall Superbass with the same versatility as a POD XT. On the Bogner, I can get a Twin all the way to massive crushing gain, and every vintage Marshall tone in plexi mode. They cost a lot, but they're pure joy to plug into. Read the harmony reviews on the Ecstasy 101B. There's guys who've used every amp, and they rave about the Bogner. I just retubed it again, and it's a thoroughbred killing machine! I've started messing with the Class A mode a lot more, and the clean tones are shimmering and beautiful. It's always surprising that an amp that can do great gain tones can also sound better than my Matchless on cleans. It's the last thing I'd ever sell.
One feature on mine that I haven't even used yet is cabinet assigning. One of these days, I'll take the back off my Bogner 2-12, and assign the clean channel to that, then assign the blue and red channels to the closed back 4-12. Maybe I'll do that tonight, and see how that feature is.
