I'm building a p-bass and have it already routed out to fit a precision neck. But I have decided I want a jazz neck on it. Does anyone know if the heel and bolt patterns are the same?
P and J heel dimensions are the same. There are two ways to guarantee a perfect hole pattern match; 1) A virgin neck. 2) Plug and re-drill a donor neck. If the hole pattern is really close, I just enlarge the screw holes in the body a little.
