Neck suddenly needs a shim
Hi. I've this (allegedly) Fender body with a Roytek fretless neck stuck to it. The truss rod wasn't strong enough to keep it straight, so i tried unmounting and reverse clamping it. It didn't help, and moreover now i can't setthe action low enough. I don't recall there was a shim in there when i took it apart (weeks ago) so i'm wondering what the issue is, since i did nothing to the pocket or the neck heel. So it must be a mounting issue. What have i done wrong?
(And by the way, any way to check if the body is actually a Fender? There's no serial number or Fender neck plate, though the pickups don't look, and more importantly don't sound, like Krapteks.)
