My drummer recently acquired one of these, and I used it for practice today.
1 15" speaker, EL84s and 12Ax7s, basically a Classic 50 with a 15" speaker as opposed to 4 10"s or 2 12"s.
Has a very large sound although it's a bit lower in saturation than my amp. A little easier to use, and looks pretty boss in it's tweed shell.

How much do these go for on average used?
Sounds like an old Delta Blues model.
