+1 to the LB30/CTM30. Great amps. I've owned both guises, and the matching, extremely rare LB212. Probably my favourite rig I've owned, but not really giggable in the bands I was in with no PA support.
Not sold on the CTM15 yet. As you turn up the gain it cuts a LOT of bass so there's a few mods I'd like to make to mine which I'll report back on. It's not a full valve amp (despite what Ashdown may have said about it in advertising/interview), but a solid state front end and valve power amp, no DI. With gain all the way down it sounds very nice...
