Description
If you’ve ever wrestled with the quirks of the stock Rickenbacker 4003 “horseshoe” bridge pickup, the SRB-1 is Seymour Duncan’s answer. It swaps out that vintage single-coil design for a humbucker built around dual Alnico 5 blade magnets, giving you noticeably more power, longer sustain, and a wider tonal window to work with — all while cancelling the hum that comes with the original setup.
This bridge model is part of a calibrated neck-and-bridge pairing, so if you’re upgrading both positions, the two pickups are voiced to complement each other rather than fight for headroom. That combination suits players chasing punchy pop, gritty blues, classic rock chug, or full-on heavy rock tones — anywhere you want a Rickenbacker to hit harder and sit quieter in the mix.
A few practical notes for the install: this bridge unit ships with a four-conductor hookup cable for wiring flexibility, and it includes a phenolic surround that cleans up the look where the pickup sits. Because the SRB-1 is purpose-built for the 4003 bass and directly replaces the horseshoe magnet assembly, your original chrome mounting ring won’t fit it — plan your hardware accordingly before you start the swap.
