  • Anatomy of the 500T / magnet orientation for multi-magnet pickups

    Hey!

    I'm just wondering what the magnet orientation should be for a pickup like the 500T, which features a large center ceramic magnet, as well as two ceramic, magnetic spacers for additional kick.

    I magnet swap compulsively, and tried putting in A5 spacers. The drop in output was significant, which is understandable given the lower strength of an A5, but it seemed like a bit tooo much of a drop. From my understanding of it, in the case of the humbuckers of this design, all magnets are supposed to be oriented the same direction, so they would actually be repelling / slightly degaussing each other over time. Am I right about that?

    This magnet orientation is slightly different than in a P90, wherein you have the same pole of the bar magnet touching (e.g., south) touching the pole pieces, so the two magnets are actually repelling one another. Am I right about this?

    Thank you!__PRESENT

      Gotcha.... so it's almost like two p90s in series, with a shared center magnet....


      ----- EDIT -----

      jeremy , just corrected the prior mag swap using what you told me - worked like a charm. Thanks brother!

              Bar magnets are commonly seen fitted to Humbuckers and P90s, but occasionally turn up on some bass and single coil pickups, fitted to the underside of steel poles.


              Axes R Us has a great selection. A2, 3, 5, and ceramic!
