There are many members here who are enjoying the joys of old school ‘heavyweight’ amps (Trace in this case) paired with lightweight cabs. There are a few threads on the subject.
I’ve had several Trace SMX heads (250, 350, 600) plus a few other TE heads (including a Hexavalve) and they have all sounded great with various Barefaced and TecAmp lightweight cabs. They don’t give ‘the’ sound that you get from some of the older heavyweight cabs, but they do make up for it in sheer volume, portability and superior sound dispersion (IMHO).
