It is indeed flat, and I definitely thought about that. Ultimately, though, I think I'm gonna back burner the Dano convertible for now. I still gotta finish the P bass and put the V4 back together.Is the back flat? If so (and perhaps even if not, with tedious shimming and measuring and shimming...) router-planing it off is one method - or the old heat and a palette knife (or puttyknife or butterknife) approach.
