Could anyone point me in the direction of a replacement neck for an Ibanez TR50? It doesn't have to be an Ibanez neck; I picked up a loaded body for a project. If I gotta do some sanding to make it fit, that's fine. Looking at some photos I've seen of some other TR50 necks and bodies, it looks like the neck has a rounded heel with a 22 fret extended fretboard. It looks like a 21 fret neck would work lengthwise. I may be wrong about that, so please correct me if I am. Thx.
