I've been switching back and forth between Fender Precision and Jazz basses for years ( 4 string variety). I swear I'm going to have a custom neck made with a nut width of 1 9/16 inches, that is exactly between the P-Bass & Jazz bass nut widths (1 5/8 vs 1 1/2 inches). Bottom line, the P-Bass neck is wider than it needs to be to play easily, -AND- the Jazz bass is just TOO NARROW (and string spacing too tight) below the 5th fret or so. Don't get me wrong, I can get used to either if I stick to only one bass for a while; but 1 9/16 would be a better overall fit, at least for me. ??? ANYBODY else feel the SAME WAY ??? Who would you suggest to make a custom neck??? Fender, are you listening??? ...NO!
