I have a Marshall DSL and its raw and unprocessed and covers many tones. a Carvin is too much similar to a compressed type tone. ! dont wanna sound solid state but a lot less balls then a marshall.
I would rather have a one trick pony that does that trick perfectly if it is the only trick I need.
that being said, I dont own and havent played either of these so I have nothing useful to say. And I really couldnt get by with a one trick pony cause I do more covers than anything else.
