I had it between 2002-2003, I think. The electronics sound the same as when I had it: Bart pickups, 3 band, non-functional switch. It has an amazingly big sound for such a small instrument.
I ended up selling it back to the guy I bought it from (he loved the neck as well), who is probably the same guy you bought it from.
I had considered refinishing the bass, but that yellow grows on you after awhile. It is such a unique instrument I think it is perfect the way it is.
