I am a gigging guitar player. And I get called to play bass occasionally, or when our bass player is sick. So I need an amp that I can play gigs with. Usually restaurants, small bars, but occasionally small clubs. I have a 1970 Made In Japan Jazz bass with standard passive pickups. I play traditional blues like BB King and Muddy Waters sort of things. We don't play overly loud. Since this isn't a daily thing for me, I want to spend as little money as possible for a decent bass amp. But I don't want a piece of crap either. I also don't want to be under powered because I want a fairly clean bass tone. I would prefer not to run the bass into the PA. I want a combo if possible but I will consider a head and cab. It has to be portable. Doesn't have to be pretty or have a special name on it. Just something to get a job done. What do you think I should be looking at? Thanks for your help.
