I think it’s worth bearing in mind that if you bought this, and then later decided to move it on, all the questions you’re asking now will get asked by potential buyers. I’d imagine plenty of them would have reservations about the same things we’ve discussed here, so it might not be the easiest bass to sell. If it’s a great player, then you might be ok, but if it’s not (and a warped neck won’t help) then I fear you’d be stuck with a bit of a dog.
