Jazz Body with Precision Neck

I don't believe that for one minute. The fact that "in your opinion" one particular neck has changed the tone of your bass is very subjective. Merely the fact you "think" the tone will change is all your mind needs to "hear" a difference.
I personally don't think you could hear the difference. I have changed the neck on several instruments and haven't noticed this.
I believe that the density and weight of the jazz neck could be greater than the P neck just as easily. Especially if different woods, more "Meat/mass" as you said and what would happen then?

Wow, if you don't hear even a little difference when you switch necks, I think you maybe a little tone-deaf.
 
It would be cool if there were bound and blocked P necks.
There is, I have a Warmoth Precision neck with blocks and binding

To clarify, for @madjazzbass, I meant when changing like for like. As in maple/rosewood p neck swap for maple/rosewood jazz neck. Which I have done with no discernible difference.
Obviously if the swap is not "like for like" and you go maple/rosewood to maple/maple there is an audible difference, in my experience. And while I do have some hearing loss my ears are still pretty good at hearing small changes in tonality. So says my recording engineer/studio owner buddy, And I know he's not blowing smoke.

There will be a difference for sure. The problem is when people try and pin the difference down, and try and attribute it to something specific. Imagine you slackened off the strings on your bass, took the neck off, screwed the neck back on and restrung the bass. It might sound different, right? The strings have subtly different break angles over the nut, the neck bolts are tighter/less tight than before or the strings sound different simply for being slackened off and then tightened up again. You can't extrapolate this up to repeatable, predictable results however. I'm not going to rush out and buy a rosewood Jazz neck to replace a maple Precision neck, simply because I'm sure that the swap will result in an easily identified and measured improvement in tone.

?Hmmm; Sorry to hear of your (hearing) loss, but all of the swaps I've done were Maple (Jazz) to Maple (Precision), I don't particularly care for Rosewood fingerboard, but when the swaps were done (Jazz neck to Precision neck), each time there was a Very noticeable difference in tone; seems to me that it'd be pretty obvious to most, but, I guess we all hear things differently.

The two J's on the floor stands both have Precision necks, they both have a fuller, a broader and a warmer tone now than when they had actual Jazz Bass necks on them; that may not be a tone a lot of Jazz Bass players want or like, but I Love the tones that I get from my two J's w/ Precision necks.

You know you can only play one at a time, right?

(... 'the density and weight of the jazz neck could be greater than the P neck just as easily'). Really? In what Universe? ...and What kind of wood would that Jazz neck be made of that would give it so much density and weight? Petrified wood? :woot:
 
After all the "tinkering" with Basses I've done over the years, changing pickups, Bridges, necks, pots, strings, tuners what have you; and especially after my Warmoth build and my latest parts Bass, I finally found what the best combination is for the perfect Bass ... (well, at least what works for me), and that's a Jazz Bass body and a Precision Bass neck. I know a lot of guys are always like, (in a whinny voice ) "I want a Precision Bass with a Jazz neck", Phooey! A thick solid Precision neck (made with quality woods) sounds much better, much warmer, punchier and resonates better than any pencil thin Jazz Bass neck, trust me, I have 7 Jazz Basses, 2 Precision P/J Basses and 1 Jazz w/ a Precision neck and all the ones with the thicker necks just sound fuller and richer, they have a certain warmth to them that a Jazz Bass neck just doesn't have; you have a thin neck, you're going to have a thin(ner)sound/tone, that's just me speaking from my experiences. If you happen to have any spare parts laying around Jazz body and a Precision neck, Try It, You'll see what I mean. So that's what my next Warmoth build will be, then I'll sell off a few Basses that hardly get played anymore. Alright, I done with my rant, Let me have it, I don't mind, I can take it.
 
I think the Fender Mark Hoppus signature bass had a jazz body with a precision neck, with a reverse Seymour Duncan quarter pounder Split pickup. I wish they still made these they looked great, a seafoam green jazz body with a pearloid pick guard and a rosewood p neck. Whether you like the player or don't is besides the point, this bass is a beast. He played stingrays early on but Jerry Finn produced the enema of the state record and like a lot of producers prefers how precisions sit in the mix especially in the studio. So he has been playing fender precisions ever since. A beast of a bass with massive sustain.

OK, I'm "tone deaf", you win, Geez!! :banghead::rollno:
 
Sorry, meant no offense. I do believe that some things can change the sound of an instrument. I’d would love to have heard the A-B. And hear the difference for myself.
I’ve just never heard that on neck changes but I have only changed one maple fender neck for another. As for necks they can be made of different woods. Even every piece of the same type of wood has a slightly different weight and density.

Been thinking about this a bit recently as weight becomes more and more a preoccupation of mine. P-bass bodies are usually lighter than J-bass bodies simply by virtue of their smaller size. All things being equal and assuming you could have the J-bass pickups/electronics and position of your choice would you still put a P neck on a Jazz bass or just have a P-bass with Jazz pups/controls/etc?

Not sure how many here know about these but it’s a Jazz Bass with a nice beefy neck and a 42mm nut width. They are also very light, under 8 pounds. Been looking for all this in a Jazz Bass for years with no success. Oh and the best part, they are only $69!

I read the thread about those recently. I'm not convinced of all the hype, but it does seem to be notably more than $69 dollars worth of bass.
