well, i run it thru a carvin c412t 4x12 .. i think it was the stock cab that came w/ it when it was new.
it was the amp replaced by the MTS series .. which are generally more gain-y. this has a very legacy-ish character to it .. especially with EL34s. Needs lots of volume to sound tasty, but that's a
tube amp truth

As for what it sounds like .. i dunno .. a marshall but a lot tastier? i hate the marshall sound but love this amp .. geez.. maybe try the carvin.com boards for a more subjective opinion?
