    One of the questions we're asked frequently is about the proper placement of the threaded CuNiFe magnets in an original Fender Wide Range Humbucker.

    According to Fender's original documentation, the magnets should be installed as shown in the diagram below.

    I hope this helps some of the confusion often associated with these pickups.

    This diagram shows the pickup as viewed from the top.

    Nice drawing. I'll save it with my tech stuff. Are both pickups oriented the same way, i.e. S poles towards the headstock?

    Yes. For original vintage WRHBs they're all made the same way.

    We have run across some with the north coil closer to the fingerboard, but according to the original Fender drawing, the south coil is as shown.

    Can you speak to what normal magnetic strength is and how to measure it with a multi-meter (or if something else is required)?
    Can the magnet strength be measured with pole pieces installed? How can one verify that the polarization is correct; I see the diagram but how can one tell if the pole pieces are installed properly (which end should attract/repel, etc.)
    Thx

    Stew Mac sells a magnet polatiry tester that is very inexpensive.

    You would need a gauss meter to check the magnet's strength and each magnet gets tested individually.

    But magnets can be tested while installed in pickup?

    Thx for the response.

    With the Stew Mac tester, yes, you can test them while they're in the pickup.

    This is the way we were making our pickups. Fender made theirs both ways with the South magnets near the neck or the North magnets near the neck. We did ours this way because they matched better with about 90% of the bridge pickups out there.
    Hope this helps.
