Hi all, I was recently at guitar center and they had an Ibanez P that appears to be from 1977 (CK770079 s/n). It's well worn with some checking on the back but overall in fair shape for something that old. They wanted $499 for it and since it was easily the equal of some of the genuine F basses there, I went ahead and took the plunge figuring that even as a "vintage" piece, I have three days to decide if I'm happy with the price. Once i started looking around more, now I'm not even sure its authentic. It's a bit unusual in that its truss rod adjustment is at the heel and it has a small rout to leave it open for adjustments via hex wrench. There's no cover at the top and it has a stripe down the back of its neck. None of which appear in the more common threads I've found on these basses (which normally have a white truss rod cover at the nut). The neckplate s/n only loosely matches the examples given online, and I've seen no reference to having a two letter prefix. The other thing that seems odd to me is that the neck seems to be less worn than the body, which makes me wonder if it had a neck swap or refinish done. I'll post some pics in the morning, but while I got along well with the bass at the shop, I'm not convinced I even bought what I thought I did. On one hand, it plays good and sounds good. But if I overpaid by more than a small amount, I'll probably look back on the whole thing with regret more than joy. Thanks in advance. Any insights, perspectives or advice are appreciated. Edit: Bump with a link to photos of the bass.
