It's not yet another cabinet. It's a speaker-equipped tray table
I can't believe the difference between the 1960 and the MG412 cabs. I've been playing the DSL40C through an MG412 for a few weeks now and thought it sounded pretty good. After firing the 1960 up and hearing how it sounds I'm ready to toss the MG412 in the dumpster.
Sell that cab to save up money for a cab with Greenbacks as well, for another flavor.
