Close mic it with a SM57 like your favorite recordings probably did. You don't need any fancy room treatment when close micing. Or just run the direct input through an amp sim and cab impulse response. Unless you're going for a 1950s sound where mechanical speaker distortion actually matters, IRs capture the cab/mic sound very well.
