Hey Pierre, fender humbucker pickup is not so friendly to mod, this pickup has a coil extended to make this tap thing, its not so easy to rewired, and terminals on the pickup not accept heat, if you touch with the solder iron, plastic melts and force the terminal up, and this will break the coil (ask me how i know that! Not fun at all)
Look like its magnetic problem, reversing the magnet on bridge pickup will make this in phase with original middle pickup, solving H + S on 2 position, and when tap a bobin you have one bobbin with (north ou south) engaged, if you flip the magnet everything is in phase.
We need reverse wound and reverse polarity to had everything in phase and no hum. I believe when you change the middle pickup wire, its in phase, but with reverse polarity.
So, the easy way is! Rewire the middle pickup to original ground and hot. In the bridge pickup, remove the baseplate and flip the magnetic bar of bridge pick-up to get everything in phase, just mark one side of the magnet with a arrow up, remove the screws of base plate, apply some heat to melt the paraffin wax and rotate the magnet (bar magnets have poles in the sides, so, arrow down to reverse de magnet).
If cancel hum in 2 position with tap on, everything is in phase.

if you use a regular jaguar pickup, remember to solder a ground wire in the claw like a tele neck 3 wire pickup

Hey Andrew, neck has the original frets? Sometimes refret with a fret tang thicker than original make a backbow compression.
Last week I put a fender neck in compression with a stell plate and 2 spacers and give him some heat and let cool down under pressure, save the neck too! Low heat to preserve the finish.

i think i find the problem with this guitar, when nothing worked i tried to make the problem more obvious and over tight the truss rod, nothing strange happens (in get even curve in neck side to side). So i tried the other way, i loose the truss rod and its a 2 way truss rod, so front bow do the max and i see the problem, i dont know but i believe the fretboard is not glued properly to neck in Low E side, not a fixed hump in one side of the neck, adjusting the relief make the neck twist and “fold” like a compressed rubber. The heel is more stiff and a lot of the forces work in this area . Its like the high E side is a lot of more stiffer then the low E (maybe the rattling i hear is a reinforced carbon rod loose?)
To get this i use my continuity tester, put the guitar to neck jig, setup the guitar and use one probe on the straight edge and other to frets, even if i set a half step down on low E make the neck shift one side and buzz from start all over again.

Hey Matt, you can use a capacitor too, the values is on the image!

Hey Pierre! Its not a complicated process, chances to snap a wire are very low (wire from fender pickup humbucker goes directly to terminals, no “pig tail”. It’s 4 screws out, heat from a blow dryer and everything come a part!
Try in a few dead or not so expensive pickups before, it’s a huge gain for your shop and clients stay very happy!
Know your limits is always a great and positive thing too!

Thanks Ian! It’s a brand new guitar, client contact the dealership and it’s in process to return and get other one.
I really want to open and understand why this happened, not know why it’s a big bummer, all of 3 have a fingerboard. But first 2 don’t have a 2 way truss rod. Maybe the next owner let me do it or sell me the neck!
But one strange guitar for one decade of work is enough for me!

Hey Ian, thank you for the reply! Yes, i tap the back of neck, back plates and nothing. I will list everything i work
-Strings: Change the ernie ball, install a new daddario set, and tried a other E string just in case.
-Nut: File and prepare every slot, make a relief for string, adjust height, remove the excess (this nut came so high from factory), check if is fitted and glued
-Frets: Fretwork in the neck jig, Check if every fret is glued, level and shaped right, check with 3 sizes of straight edge to tried to find something local
-Bridge: File all the contact points in saddle to correct the radius and make the intonation.
-Hardware: Check if any screw is loose, check from side move in saddles or loose screws in tune o matic, remove the back plates and truss rod cover, tuners tight in place, strap bottom ok, pickups ok (its not hi to pull strings), pickup springs not loose, pickups screw ok. pots, switch and jack ok, all inlays, binding and wires.
No overset for the neck.
Today i notice when i play the last fret i can hear something like a washer rattling very low in truss rod access on headstock, i taped the strings in headstock, put felter pads in bridge, tried everything i can to isolate the problem.
I didn’t make a fall away in frets this time (client decide to return the guitar), i remember to try this on the other 2 cases and make no diference at all
