Wow, $220 is a STEAL for one of those, even with some condition issues. Assuming the neck is OK, etc., you could clean that up and flip it for 1K, no problem. You probably know all of that already, but great find.
Also, I realize this is an old thread, but I can confirm that the plus series basses are not “boner” basses. I have seen people occasionally/erroneously refer anything from this period as a “boner” bass, and the confusion is understandable since they’re from the same era and these models were made at the same time, but what the “boner” name really refers to are the standard models from this era, which had the redesigned body with the elongated horn. I think they did it to add balance for the 22 fret neck. People didn’t like it, for obvious reasons, but they’re actually great basses. I own a ‘94 boner jazz bass, and it’s one of the best basses I’ve ever had. If any of you run across one, don’t dismiss it out of hand. They’re really good instruments.
Anyway, the plus series basses actually had slimmed down/lower profile bodies.
