I too was in your position, played electric bass/banjo/guitar for a few years, fell in love with DB.
There are many threads against CCBs (cheap chinese basses), but despite warnings I bought one anyway. $700 Merano from
www.onlineguitar.com. It arrived a few days ago, and is more beautiful than I envisioned, as far as the finish and grain go. But the important part is the sound. I can't play
well yet, but it had tons of volume and sounded good. The bridge is very high, so I'm paying about $50 to have it taken down a bit, to make it more playable. No complaints, if you have more money there are better basses, but you will get a fine working bass. Some say it is the luck of the draw, and maybe I got lucky. Worth it for me and my needs.
After you learn how to play and get/make a pickup, I don't see why it should'nt work in any bass amp. I haven't plugged mine in yet, however. Good luck!
