I'm a fan of the Bassman 400. The 400 Pro should be even better (I haven't played one though). The amp can sound real warm and clear set totally flat with no eq activated. Fender also has the 800 Pro head, the 1200 (tube preamp, used to be Sunn) and the 300 (all tube, used to be Sunn). All good sounding, giggable amps.
