a friend wants me to buy his bassman ltd. i'm not sure what year it was made, but it's recent. and i'm not sure what speakers are in it. I've never owned one and have only occasionally played through one. I understand it is a great blues and blues rock amp. and a last thought: will playing a bass through one destroy the speakers? I just want folks' thoughts about the tweed 4x10 bassman, and experiences. thank you!
