I have recently rejoined the ranks of an aspiring bass player. I have not played in over 15 years, however recently I received a bass, a practice amp and if I ever play in band again a pretty good bass rig (SWR 750 with two Cabs). I am attempting to get a better idea on what kind of bass I have. This is what I know; it is an Ibanez BTB from 1999, it was made in japan, it as a translucent black/purplish/gray finish. I think it is a a BTB 500. That is all I know, I was given everything however there was no documentation for the bass. I have all of the documentation concerning the amps. So please help. Below are some of the questions I have, also if you any other info concerning this bass please share. 1 How are the electronics, should they be replaced. I noticed that he newer models have Bartolini electronics. 2. So how do the older models compare to the new ones. 3. What kind of body is it.
