Rayman Posted May 23, 2023 Share Posted May 23, 2023 I bought a used set of the Alan Entwhistle pickups for a project. Unfortunately in the process one of the magnets popped off the bottom of the J pickup. Does it matter which way round it goes back on? Or is it “just a magnet” that you whack back in there and crack on? Quote Link to comment Share on other sites More sharing options...

Good news is it's easy fixed 🙂 Just look at the magnet, there should be signs of glue or sticky label. Either match the sticky label or put it on glue face down 👍 1 Quote Link to comment Share on other sites More sharing options...
Rayman Posted May 23, 2023 Author Share Posted May 23, 2023 Thanks mate…. Yeah I just figured out exactly that. Not much evidence of the glue unfortunately, so there’s guesswork involved 🤔 Quote Link to comment Share on other sites More sharing options...
Rayman Posted May 23, 2023 Author Share Posted May 23, 2023 There’s 4 magnets on the bottom of the J pickup as per usual, but should they touch in the middle? Or should there be a gap between them? Quote Link to comment Share on other sites More sharing options...
Rayman Posted May 23, 2023 Author Share Posted May 23, 2023 So should they attract each other or repel each other in the middle? Quote Link to comment Share on other sites More sharing options...
PaulThePlug Posted May 23, 2023 Share Posted May 23, 2023 (edited) I would imagine attract each other... Some pics here.. https://reverb.com/item/56383159-entwistle-jbxn-bass-bridge-and-neck-w-neodymium-magnets-2021-black Can you not see glue outline left on the bobbin,or residue on the magney Edited May 23, 2023 by PaulThePlug Quote Link to comment Share on other sites More sharing options...
Rayman Posted May 23, 2023 Author Share Posted May 23, 2023 That’s the irritating part, the magnets are really clean on all sides, hard to tell which way they go back in. Once back together and all hooked up again, the bridge (jazz) pickup is out of phase (sounds very weak). So it needs to come out again Quote Link to comment Share on other sites More sharing options...
Rayman Posted May 23, 2023 Author Share Posted May 23, 2023 I don’t have the patience to keep messing around with it. I think I’ll pull it out and replace it with something else. Quote Link to comment Share on other sites More sharing options...

Not sure I care anymore 🤦🏻♂️ Quote Link to comment Share on other sites More sharing options...
kodiakblair Posted May 24, 2023 Share Posted May 24, 2023 I dug a set of JBXN out the drawer last night, the magnets meet in the middle. Another thing was the polarity is reversed, neck and bridge will snap together so watch your fingers 😁 I wonder if you might have the split coil the same polarity as the single coil and that's causing the phase issue.

Rayman Posted May 24, 2023 Author Share Posted May 24, 2023 Hmmm interesting. It’s frustrating to me because I’m fine with most tech stuff, but electronics are my Achilles heel, and pickups are a mystery to me. The problem was that the covers are really chunky and wouldn’t fit in the routs, so I popped the covers off top put them into the original Fender ones (into which they fit perfectly), but in so doing the jazz pup magnets dislodged. I haven’t a clue how they go back together. For the sake of 25 quid for a new one, I might just do that…. OR, go for something else. Quote Link to comment Share on other sites More sharing options...

Some place in this bloody tip of a house is a compass, if I could find it you'd know what way the magnets should be in no time 🤬 1 Quote Link to comment Share on other sites More sharing options...
Aidan63 Posted May 25, 2023 Share Posted May 25, 2023 email Alan, he's super helpful ime, he can probably tell you how to reassemble correctly. There must be a process they follow in the factory to ensure correct polarity and phase so that the pickups sound as good as possible and match as pairs; he may well have something to advise about PJ set up as afaik they don't sell PJ sets, but obviously they can be made up buying single pickups, which may or not be ideal ? Is there a standard for polarity for neck and bridge 'jazz' pickups, if so it should be published and manufacturers follow it (or not) ?
