Swart amps could be loosely described as "somewhere in-between tweed and blackface"... the original Swart, the AST, used a Gibson Falcon as it's inspiration, I believe.
Less headroom and more mids than blackface amps, but more headroom and less mids than tweeds.... does this make them similar to brown/blonde Fenders? I know they are very popular with owners... from everything I've read over the last dozen years, most owners don't sell them. An AST (a MKII, actually) has been on my bucket list for awhile.
