Hi, I'm wondering if anybody out there has any experience with Marshall bass cabs. My local music store has a good deal on a 4x12. It's their top of the line cab. I didn't even realize they made bass rigs. 12" speakers seem kind of unusual in a bass cab, but I know their reputation for guitar amps, so I wonder why you don't see many bass players using their stuff. If anyone has had any negative or positive experiences with them, I'd like your opinion. Thanks in advance, Len.
