When the pickups were upgraded, did they rewire it without the switch? Is that what I'm understanding?

Here she be with some of my others. It's an atk 300 behind it, a Carvin CT3 or whatever the hell they call it, one of their factory bolt strat copies (not a kit) a takamine acoustic and a zeta x104. Also missing is a tele and a Carvin LB70. If you can't tell, I like Fenders and Carvins 
The switch was removed, so the tone control is the knob closest to the split coil, the split coil volume is next and the single volume is after that.

By only beef is I just had the best tech I know set it up and the action still feels a little high for slap. I'm much more fluid and rhythmic on the Ibanez. To be fair, my brain is also kind of broken.

Awesome! I can't abide that P/J headstock on it, though; to me, part of the charm of the JP90 is the narrower headstock.
Still, you're #43! Welcome!
I didn't even know there was a difference! I wonder if someone makes an aftermarket JP-90 neck with the right headstock? Warmoth maybe. I just had it setup and it sounds fantastic, but the action still feels a bit high for slap, some of it just may be me getting used to it, but I feel like my pops in particular are suffering. The tech is coming by my house tomorrow so we'll take a look. Really happy with this bass overall and think for $400.00 I got a bargain

Yes, the JP90 has a headstock shaped like an enlarged version of a pre-CBS Stratocaster. If you’re crafty, about 20 seconds with a spokeshave would do the job… you’d just be removing some wood from the slightly curved part of the headstock, underneath where the Fender logo goes.
You could use a rasp, then a file, then sandpaper too, but you’d need to be more careful. It’s all cosmetic, though.
Well a couple of things to know first. The factory pickups are filled with epoxy and the covers don’t come off.
The p-pickup is standard size. The bridge pickup on the JP 90 is neck sized, though I think some of the early ones had a bridge size pickup.
May not be able to change the look without new pickups.

Pics are probably few pages back
Well, my aftermarket neck truss rod seems to be toast. My luthier friend set it up, it instantly bowed to crazy high action. He reset it and a couple of weeks later the same thing happened. It’s not a fender quality neck anyways. I ended up buying a brand new roasted maple neck at his suggestion as I live less than a mile from the ocean and he finds they are more stable. It will be here on Wednesday. I should have it back sometime next week. I think it will look cool to have the fender logos etc on it and the color will look great too with the torino red. It also has fatter frets and after my my buddy dials everything in I can’t wait to try it. The tone with the bass lines pickups on this bass is great.
The one thing I have struggled with is pops when playing slap. It just doesn’t seem to have the same power as on my Carvin LB70 and my OG Japanese Atk 300. It could be the strings or have something to do with the neck. Does anyone have any thoughts on this?
I am hoping if I remove the truss rod from the old neck I’ll be able to put some washers on the truss rod and see if I can salvage it for a diy build where I either machine my own body or buy some el cheapo spare locally.

So just an FYI, I was never able to save what apparently was a mighty mite neck. I ended up buying a roasted maple MIM neck as my luthier pal said it was a better investment for stability in our costal climate than even an MIA regular maple neck. I have to say it has completely transformed the bass. I now am totally in love with it. The new neck, the bass lines pickups and j-bass style wiring has made this into the first bass I’ve liked as much as my long missed American Deluxe J-Bass and my Carvin LB70.
Good replacement choice!
Sounded like you were going to invext in correcting the old neck-- banging your head against the wall--
I went with a Warmoth birdseye maple years ago (can see on an earlier post)
Got a good price... Saved a lot of headache trying to fix a "whammy" neck...
So, im glad you got the roasted neck, hope you get many, many gigs out of it!!
I’ll snap one tomorrow. I’ve been recovering from a series of brain surgeries and a lot of my other hobbies are off the table so I’ve been rebuilding and playing with my bass and guitars. I’m so happy with the jp90. I just want to get the vintage style top hat knobs for it. It had tele style knobs now.
I just finished a squire Fretless build. A friend gave me a young Chang 1988 neck that was badly de-fretted. I got to enjoy the process of filling with rosewood dust (with a full properly equipped respirator) and then 4 hours of sanding to change from a 12.5” radius to 12”. I missed the memo on it being that extra 1/2” of flatness so I ended up going from 6@ to 7000 grit with a 12” radius block. Really happy with that too.
I have always loved fender basses and so regretted selling my American deluxe j bass. This jp-90 is even better! I love the p/j pickup combo and once I get a half way decent bridge and pickups on the parts Fretless j bass, I think that will be a real winner. It actually sounds and plays great with all the parts after extensive shimming and setup. I think after hearing the bass lines pickups on the jp-90 I know there’s a lot to be gained from some electronics upgrades.
I wish the roasted maple neck was MIA but I have to say the quality and finish of the frets matches my previous MIA bass necks. If I find another one of these jp-90s cheap. It’s headed to a Fretless conversion!

I've been lurking here for months. I bought a beat-up JP-90 months back. I have a nice Fender Prodigy, which is basically an active JP-90, without a pick-guard. I love the neck on the Prodigy so I've wanted to buy a JP-90. The prices have gone way up on these (around $1,000). I found a beat-up 1990 model and began to restore and mod. I took out all of the Mexican hard-wear, and replaced with the US equivalent, to keep the vibe. US reissue 70's Jazz Bass bridge, and Hipshot HB-7 tuners. All dropped in with no new holes. Got a Fender Corona neck-plate as well. The artic-white paint had changed to a cream color, due to nicotine I guess, There was a big gash, down to the wood. Used Milliput to fill, and my wife mixed some hobby paint, and hit very close to the cream shade....you can't tell unless you are really looking. The worrisome part was the neck--the action was very high from the 9th fret down, and I couldn't get it set.
Luckily, I am near a very good luthier, and he got the neck set perfect...I could adjust and tweek the action to just where I wanted. He also dropped in some Fender Yosemite pick-ups and a new tortoise shell pick-guard, and now it is a new US Fender Bass that looks and plays smooth

That's beautiful, @fingercuff !

Thanks guys. I read everything in this "club" about the JP-90, and it really helped in the process. The posts are very informative. I wish there was a Prodigy Club like this.
This is so exciting! I thought I was alone!
I couldn't sleep, so I decided (again) to try to figure out if there is anything at all I can do about the bowed neck on my beloved JP90, and I stumbled across this. I haven't read through the thread yet, because I was too stoked not to jump to the end and say hi, but at a glance it looks like there are lots of ideas for replacement necks, pickup upgrades, and other modifications. Plus a bunch of pictures of my baby's siblings! I'm very much looking forward to reading through it all.
I need to clean mine up and do some work on it. It still sounds great...sonically it's my favorite bass I've ever had. I just want to get it back to where the action isn't so high I'm pulling muscles in my fingers when I play.
Anyway, can I join the club? I'll put up some pictures...

Speaking of late to the party...RockinRobert, I don't know if you will ever see this post, but WOW I love the look of the wood on your stripped JP90. I considered stripping my red one many years ago but convinced myself the wood wouldn't look right. I may need to reconsider....
