Decided on swapping out a neck on a Jazz I don't play much, and wow! I don't particularly like blocks on a P, and I prefer the 1.625 nut width, but as a temporary measure this is great.
The neck fit like a glove, didn't so much have to adjust the truss rod once it was strung up, and the satin finish has made the bass so much quicker to play. I love the CAR/black/maple colour scheme anyway, and I think it looks great here.
It's a VM Jazz neck (previous owner replaced the decal with the Fender logo), on the VM CAR PJ body. The only other mods I've made to it so far are putting in a 3 way pickup selector, with one vol & one tone control, a switchcraft jack, and I believe my tech swapped out the mini pots to full size ones, and routed out a little more space for them.
Considering swapping in some SD SJB-2s, as I've never tried them and would like to give them a blast. Otherwise, I'm still very happy with this bass - it plays better than some Fenders I've paid over twice the price for.
If they made these with maple boards as standard, I'd buy a LPB tomorrow. Tempted to get a 3TSB and keep it stock, too. I don't think this'll be my main player, but I'm tempted to use it as my sole instrument for one band, because it's the one I keep picking up first right now.
