Thunder'Mag Bridge - Universal Mount

  • Thunder’Mag - Bridge - Universal Mount

    The unique tone of the Thunder’Mag is the result of offset T-Armond cylinder magnets which ensue a quick attack with exceptional pop and clarity followed by a voluptuous bottom-end.


    The Thunder’Mag has been described as Rickenbacker-esque but more dynamic and less aggressive i.e. not harsh in the top-end eq. Out of our three bass pickups, you will notice the most definition with your fingers/pick in the Thunder’Mag. Definitely a great choice if you want to cover a lot of genres, because it rounds out nicely with a tone control.


    The Universal Mount is a direct drop-in replacement for standard sized Filter'trons - with and without "ears" or “clips”. This pickup comes with two pieces of compression rubber, 2 mounting (wood) screws, and the Universal Mount Clip Pack which includes everything you will need to mount the pickups to your ring or pickguard. Please refer to the Tech Specs tab to learn more.

  • Output/Power

    DC Resistance is not entirely an indicator of true pickup output, although it can be helpful.

    Bridge: DCR - 8.0k / Inductance - 2.75H

    Neck: DCR - 5.0k / Inductance - 1.13H

    Wiring Notes

    This pickup is shipped with 4-conductor wire but is ready for standard 2-conductor connection. The extra red and green wires come soldered together and taped off - to split coils, send these to ground. 4-Conductor wire is also convenient for custom switching i.e. pickups combined in series or parallel.

    Helpful Notes

    Filter'tron Replacement: The Universal Mount is a direct drop in replacement for Vintage Filter'trons, HS Filter'trons, Fideli'trons, Mega'trons, Full’trons and any other standard sized 'Trons (including our old No Ears & English Mount). Blacktop Filter'trons require one Dual Screw Mount Adapter per pickup in order to attach to their stock rings. When replacing Broad'trons and Gretsch-Buckers, you will need a new EM2 Ring.

    Installing Single Pickup: If you play a single pickup bass and your pickup route is in the center (between standard neck and bridge placement) then opt for a neck pickup. If you want a more aggressive sound, opt for a bridge pickup.

    Humbucker Replacement: To replace standard Humbuckers, pair this Universal Mount with one of our EM1 (Gibson-style), EM2 (Gretsch), or EM4 (Fender-style) rings.

Customer service and ease of purchase was exceptional. Being able to chat live online with staff was a big plus when questions arose. I Haven't installed the pickup yet, but build quality is clearly above top-notch and the options were exactly as ordered. Thanks TV Jones!
