I asked Mr. KBRoscoe about neck and body swap possibilities once. He said that swapping is typically infeasible, as necks and bodies of same models rarely interchange, and necks and bodies of different models are, as a rule, incompatible.
I think this is something that separates Roscoe from other builders. While bodies and necks are made in “batches” that doesn’t mean mass produced and interchangeable. In the end, be it a standard or a custom, the neck is fit to it’s intended bass by a person. At least I believe that’s the way it works.
