I used for some gigs this combo. added a tubeman plus preamp in the rack space and combined the amp with my 4x10 Ampeg cabinet. i play in apower trio and we play seventies rock'n roll. i was really surpriesed how good the setup worked. great sound with my Precision, rickenbacker and G&L L2000 too. i am tyhinking of buying this amp. who likes the bassman 400?
