I have one that I recently purchased and have now used at two gigs and four rehearsals. I really like the sound of it so far. The guys in the band really like the tone also. You can look at my profile to see the fx I run with it, the VT Bass being the biggest outboard tone shaping pedal I use.
I bought it specifically for the reason of wanting to downsize from my old Trace Rig. I had an AH300-12 head, a 2x10 and a 1x15. Loved the tone, hated hauling it around. It fits that bill perfectly.
The ONLY thing I'm considering doing to it is swapping out the 16 ohm speakers for 8 ohm speakers so I can run it at its full 300 watts (versus 180) w/o adding an extension cabinet. I've been searching threads to find others that have done that and have only found one person so far. Fortunately, he's pleased with his results, so I'm leaning toward doing that. That issue aside, the amp sounds great. I really like the tilt-back design of the cabinet, putting it on the floor right behind me and hearing it helps on smalle rstages where space isn't a luxury.
