There is a pretty nice profile of a vintage Marshall Bluesbreaker on Rig Exchange which really has the "Beano" tone. Great for old school british blues and has that woody 2x12 open back sound that sets it apart from the usual JTM45 sound.
The author of that rig is Daniel Henriksson. Daniel, are you an active forum member by any chance?
I'd like to know a bit more of that amp and wouldn't mind more profiles as well
