I'm the lucky owner of the super redhead, i'm lucky enough to have the option
of using mine with a 2 x 10 or an 1 x 15 extension cab & i can coax any sound
i wish from it either for rock, pop,blues( jazz if i could play it) & its especially good on funk.
I haven't used the Black beauty combo myself, but i'd say it has a slightly fuller / warmer sounding bottom end
than the super redhead although i'm not sure what eq'ing options that is has available to it.
Yes it is a weighty combo, but it'll do the job for me.
Oh a quick add on which my fellow swr user JpJ forgot to mention, the redhead is rated at 240 watts @ 4 ohm
& the super redhead is rated at 350 watts @ 4ohm.
