I had the Heritage B-15 and thought it had plenty of power, I moved it on because it was too awkward / heavy and precious to gig with, it was sat looking beautiful in my front room but wasted, I gigged it a couple of times in medium venues and it was fantastic, just far too precious to gig. I now have a Mesa walkabout 15 which is my main gigging amp, I'd say equally beautiful, more head room and far easier to transport.
