Seymour Duncan SMB-4D 4-String Ceramic Magnet Pickup For Music Man
The SMB-4D delivers punchy, articulate output with the aggressive character that ceramic magnets are known for.

Hand-built in Santa Barbara, this pickup brings professional-grade construction to your Music Man bass.
Tone & Output
Ceramic bar magnets paired with a 2.6 kΩ DC resistance per coil produce a hot, responsive signal with excellent sustain. The 9.4 KHz resonant peak emphasizes upper-midrange articulation, delivering punch and clarity that sits well in dense mixes without sacrificing low-end definition—essential for cutting through on a crowded stage.
Design & Construction
Dual-coil configuration with arched pole pieces ensures balanced magnetic field and consistent response across all four strings. Vacuum wax potting and Forbon flatwork eliminate microphonic noise for road-ready reliability, while the shielded 4-conductor leadwire provides flexibility for series, parallel, or split configurations to suit your rig.
