Seymour Duncan SM-3B Seymourized Mini Humbucker 4-Conductor Bridge Pickup

The SM-3B delivers articulate, punchy output in a compact mini humbucker format designed for bridge positioning. This high-output pickup excels in guitars demanding clarity and definition without sacrificing the full harmonic character of a traditional humbucker design. Built for players who need responsive midrange presence and controlled treble in modern offset or semi-hollow instruments.

Tone & Electronics

Voiced with a 4.8 kHz resonant peak and balanced EQ voicing (7 bass / 5 mid / 6 treble), this pickup emphasizes upper-midrange articulation ideal for cutting through a mix. The 11.6 kΩ DC resistance generates high output while maintaining note separation and clarity across the frequency spectrum.

Design & Build

Constructed with high-carbon steel blade per coil coupled to a bottom-loaded Alnico V magnet, the SM-3B achieves superior sustain and dynamic response. The chrome cover provides both aesthetic appeal and magnetic shielding, while the 4-conductor cable enables flexible wiring configurations for coil-splitting or phase reversal applications.
