Dear helfpful members of UG,

My friend needs a bass amp... his budget is around $400, may go over if necessary.... amp needs to be able to perform live as he gigs a lot... I am a guitar player however and cannot give many suggestions besides try to find a good used tubed amp...

any suggestions?

Tubes aren't nearly as important in a bass amp as they are in a guitar amp. A solid state bass amp will do just fine. Hartke, Ampeg, and Gallien-Kruger all make good bass amps, however I have no idea what's available in the $400 range.
