    Hello fellow bassists, i'm currently upgrading my sweet J&D white Pbass into a main gigging bass (Duncan quarter pound pickups, fender high mass bridge and fender tuners) and the next step is to change the neck, i've seen some fender pbass necks for sale and i wonder if they would fit my J&D.
    Problem is all the ones i see are 20 frets and my J&D is 21, does that make a lot of difference (same scale length tho)?

    can anyone who owns an upgraded J&D Pbass tell me if the neck pocket is a standart Fender Pbass shape or will i have to carve (or add wood).
    Thanks!

    You can't put a 20 fret neck in a 21 fret pocket without moving the bridge or making a big spacer. Neither of which are good solutions.

    You should go ahead and get a new body. Then the upgrade will be complete.

    Thanks for your reply, but would 1 fret actually make that big of a difference in intonation (that i couldn't fix with the saddles)? and would moving the bridge be detrimental (i don't really mind drilling new holes in this cheap body)?

    Do you have half an inch of travel on your bridge saddle adjusters?

    Yeah i've got plenty of travel space, i've got one of those Fender high mass bridges, but what way would i need to move the saddles? fender_badass.jpg

    You're moving the nut closer by subtracting a fret from the neck, so...

    Just saw some J&D p bass pics and they have the longer 21st fret extension fingerboards (the neck doesn't go all the way up to the end of the fingerboard, check out the link below, for example)

    so if the new fender neck fits in the neck pocket of your J&D body, you'll be just fine with the intonation.

    (EDIT - what follows assumes that the old 21-fret neck doesn't have an overhang for the last fret: if it does, the neck already is a "20-fret" one with a 21-fret board, and as said above you won't have to move the bridge.
    If, instead, the 21st fret is not overhanging,)
    back. Away from the neck. As said, you'd need to move the saddles ~.6" towards the back part of the bridge, where the ball-ends anchor. It might be doable in your case (using a shorter spring behind the E saddle might be necessary).
    However, the silk or the rough, irregular section of the strings might end on the saddles (those for which more compensation is required, i.e. E and A). A solution for this new problem would be threading the string into a metal tubular spacer of some kind.

    Thanks for your help!
    after further inspection, my bass does have the 21st fret overhang so it should be fine with the 20 frets neck!
