Hi I was wondering if other than the size at the nut whats the diffrence between a j neck & a p neck? ie whats the thickness at the 12th fret tc both finger board & depth etc
I can get p neck cheap but not j necks here in Australia, can I modify a p neck to a j neck
I want to made a Jazz bass but necks etc in States too dear it import ( for me any way )
Other wise I might have to buy a cheap J azz bass or second hand
Thanks

There is a difference in the J bass necks in width, shape and feel. All good J replacement necks should fit in the same neck pocket without modification. I don't know what the exact dimension differences are at the 12th fret, but they definitely feel different. Maybe the Fender site can give you some hard data.

Myself, I prefer the P neck, not only for playing but for sound. That extra mass seems to make the bottom end more solid. Of course, that's the opposite of what most guys like. But I grew up playing a P and the extra size doesn't bother me a bit.

Over here, it's harder to find a P replacement neck than a J. Everyone seems to want a J.

I wouldn't modify a P neck to approximate a J neck. Way too much work and unless you are very good with hand tools and can do good refinishing, you'd have to pay someone to do it and it won't be cheap.

Your best bet, if you absolutely demand a J style neck might be to find a cheap bass with a salvageable neck.

Yes, you can modify a p to j. If you're confident with power tools and know how to set it up, then just jig it and route. Ofcourse, the easiest way is to find an existing neck.

Here's what I think I know:

Fender makes A, B and C width necks. P's usually have the C width, which is 1 3/4" at the nut. J models generally have A (1.5") or B (1 5/8") width necks. There are exceptions - some Ps did come with narrower necks. Don't ask me which.

Thickness and contouring of the back of the neck varies among models and years, and it's hard to say much about what a particular bass will be like except within a span of years or similar models. of course, you can always make a thick neck thinner, but now much thinner before the neck bows uncontrollably or you hit the truss rod cavity is a complete unknown to me.

Generally speaking, the neck bases are interchangeable, but I'm not an expert on exceptions, and I'm sure there are some.
