I'd tried a P-bass a few years ago that I thought played incredible, but it was $1100 and I was in college. I always said if I got a P-bass I'd get one like that but I thought I'd post here to try to get a bit more info. It was a 70s P-bass, not sure what year, it had a thumb rest and a metal cover over the pickup. The store employee told me it had a J-bass neck, and the J-neck was one of the reasons I liked it so much. So I was wondering if all 70s P-basses had these thinner necks, or how can I tell which ones do? Do they sound good compared to a modern P and how mcuh would one in good shape be worth? Thanks in advance for any help.
