I think a lot of have played one of those. They have been discontinued, so that's why they are cheap, as far as I know. I have one and like it a lot, even more now that it is fretless. The bridge is different from the usual Epi/Gibson three point contraption and works very well, too. The sound is a modern scooped sound, so if you are expecting a T-Bird thump out of it, you will be disappointed, and the whole thing goes dead when the battery dies - no passive capability at all. Those are all the bad things I can say about it. You will hear about neck dive, but if you move the strap button to the base of the neck and play it in a more vertical position than you would a Fender shaped guitar, it balances very well. For me, it's one of the most comfortable bass shapes made.
Cranky old man. Cranky old bass. Cranky old amp.
