OK, I'm new to the bass world. I am going to start taking lessons and I want to focus on jazz. I would like to eventually gig. Would I be better off with a new jazz-oriented bass (fretless, even?) or should I buy an amp? I have a bass to practice with - a Sterling Ray 4 S.U.B. series which was approximately $300 at the local music store. I play through my Eleven Rack's bass models (I'm a 20+ years experienced guitarist) and either listen with headphones or through my monitors. My budget is limited to $700 with maybe an additional trade-in worth $800. But let's forget the trade-in funds for initial advice. And, of course, the last option is to save the money for ... a higher end amp/bass? Or, another thought. A higher end bass and a Sansamp? Too many choices!
