    thank you, I'm looking at AMAZON but they are a mess... nice place to find fridge magnets though
    Mine are actually fridge or board magnets similar to these: https://www.amazon.com/LTKJ-100PCS-M...3551960&sr=8-2

    i am assuming the magnets diameter must match (approx.) the pole's diameter, with is 5 mm in my case
    I prefer 8mm magnets for 5mm poles. Always give perfect results. No experience with other neo sizes and numbers.
    From magnet theory I expect smaller diameter neos and less neos to produce a less focussed/less uniform axial field that may not penetrate the alnicos deeply enough.

    how to be sure I am polarizing the Pickup in the right way (north or south).
    Principle is: like poles repel and demagnetize, unlike poles attract and magnetize.
    You may use a compass to identify poles. Or get one of these:https://www.amazon.com/SEOH-Magnetic...s%2C258&sr=8-5

    Might be a good idea to practice with a scrap (strat) PU.
    If your bridge PU is good, leave it alone and never let the neos get close, not even for the fraction of a second.

      thank you, sir!
      yepp... those magnets you show kept popping up on my screen but the word "fridge" threw me off every time... i was looking for "more refined" terms like rare earths or neodymium
      thx!
      good tip on identyfing polarities!
      no scrap PUs at the moment... well, until i try to fix this one that is and depending on how it goes
      i am waiting for the repair guy to conclude if he accepts responsibility or not. he told me yesterday a new guy was doing part of the job on my guitar and he needs to ask him.

      thank you for jumping in and highlighting that point, that's exactly what i meant in the post just before yours "I've read on the SEYMOUR DUNCAN specs (vintage jazzmaster neck) that this one has a reverse polarity winding (RWRP)"

      can you be more explicit (for a person like me who has never layed a finger on a pickup before) about what do you mean by "charge them accordingly"?

      ​​​​​​​thanks again!

        No real risk to permanently damage a PU with the neos. If you accidentally demagnetized a pole, just remagnetize it. The method even allows to flip PU pole polarity.

          any comments on copperheadroads' warning? "TMost JM pickups are rw/rp so you need to charge them accordingly"

            I think he just meant: Don't change original pole polarity.
            You can use the compass to verify if neck and bridge PUs have opposite magnetic polarity, which means rw/rp PUs.

              thanks!
              now it's a matter of waiting a couple of days and see if this gentleman is going to take responsibility for demagnetizing the PU or not
              Plan B is clear now thanks to y'all

                time for an update.
                I've got my guitar back a couple of weeks ago. the tech purchased a new pickup (Seymour Duncan Vintage Jazzmaster) and replaced it at no charge.
                Everything is working well.
                He gave me back the old pickup too so I might at some point restore it, but right now I don't have any other guitars that will fit this PU.
                Thank you guys!
