J Neck on a P Body. How'd You Get There?

How was your Jazz necked P Bass constructed?

I'm surprised I'm so far the only person that's answered "lawsuit era parts". This is an old photo but I have a Taiwanese Kay KB-24 from... sometime between 1965 and 1975 that (probably) needed a neck replacement, so I bought a cheap roasted maple neck off eBay that just ended up being a Jazz neck. So far I've been happy with it.​

I looked at all of the options for awhile ... I ended up first picking up a Fender Custom Shop model that came stock with a J neck on a P body, but then lucked upon a 73 P Bass that originally came with a J neck and couldn't be happier.

80d MiJ "Jazz Bass Special" jazz neck on a P body with PJ pickups. The neck is indeed special on this one
This, I've have a JBS, sure they call it a JAZZ Bass Special, but the only thing Jazz about it is the neck, 1-1/2". Maybe also the J pup, but that can be switched off. Precision body w/ the P pup in approximately the sweet spot, it's the one 34" bass I'll keep, such a great neck.
 
Over at the J Neck P Bass Club, I've recently learned that there are more Jazz necked P Basses coming off the Fender factory line than I'd previously been aware of.

I'm curious how everyone has achieved this combo.

For the sake of simplicity, let's keep it to Fender and Fender compatible parts.

Bacchus BPB1RSM ~ P body with J neck ( 38mm nut width )
It is not just J neck, the neck heel end width also narrow than Fender ~ 62mm Vs 64mm

One of the great low cost P bass with J neck in current day market.

I didn't "get there"...I started there!

When I finally decided to pull the trigger for the first time, the one I wanted to buy was a Squier Standard Precision Bass Special in Satin Pewter Metallic.

Unfortunately, it had been discontinued for a few years, but I was undeterred. Even though I lucked into a great deal on an Export Edition Aerodyne (which I still have! :smug:), I wasn't about to let that stop me. After about six months of persistent browsing, I found a listing on a mint-condition P-Bass Special and, after a little bit of wrasslin' with my nascent case of GAS deliberation, I pulled the trigger on that one, too...

...and kept on going! :rolleyes:

Interestingly, while I still prefer a Jazz-width neck, it didn't take me too long to realize Jazz bodies and two-pickup systems were more my type...go fig!
 
I'm THAT guy that puts a P neck on a J bass
I've got several parts basses and actually have both a J neck on a P, and a P neck on a J.

From time to time, I think about switching the necks, but I like each bass very well the way they are.

Left is an 80's Kramer Pioneer Double J with an Allparts PEF-F neck

Right is a body I bought here in the TB classifieds. It's an unknown brand, but looking at the neck pocket, is almost certainly mahogany. Neck is a fretless 2015 MIM replacement neck.

Fender first showed the "narrow neck" option for the Precision Bass in the 1970 price lists, it's still in the 1978 lists but absent from the 1979 lists. It was available for right or left hand, fretted or fretless.

BTW, all modern Fender 5 strings use the same necks. My AmStd J5 has the same neck dimensions as the AmStd P I used to own.
I'll admit, I was wondering how you guys know the difference -- or at least, what difference there was. Possibly made more mysterious by the fact I've never owned/played any Fender bass. Possibly I wouldn't notice anyway??

My only P bass is an Indonesian Squier Affinity P Bass. The stock neck is comfy enough...I think it's actually the same width at the nut as a J. I bought a relatively inexpensive Squier Contemporary Active Jazz for a project. I put that neck on my P because I thought the matte charcoal finish complimented the butterscotch finish pretty well.
