I'm trying to figure out what model Tobias bass I have...It's a 4 string, bolt-on neck, with 4 knobs: volume, pickup balance, bass and treble boost and cut. It's 9 volt active electronics, J-bass style pickups with the Tobias name on them. I looked on the Tobias webpage, and could not find one that matches my configuration. I realize they may have changed over the years. I bought this one used back in 1996. I don't think it was more than a year or two old at that time. It came with a gig bag with the Tobias name on it. I love this bass! It plays well, sounds fantastic, and has never failed me. I just want to know its pedigree.... Any ideas???
