I put together a really cool parts P bass a while back. Every player who picks it up LOVES it. But it has a thin jazz neck on it. My 80s MIJ E series Fender P has this glorious baseball bat of a neck. I need something like that for this bass. But I know squat about measurements, radius, nut width, etc. What am I looking for? Aftermarket or Fender is fine. Prefer a rosewood board. What are some known fatter P bass necks?
