Seymour Duncan SJB-3 Quarter Pound Jazz Bass Bridge Pickup - 4-String | No Limit Guitar Co, Idaho Falls
The Seymour Duncan SJB-3 Quarter Pound Jazz Bass bridge pickup delivers high-output punch and massive attitude while maintaining the articulation and detailed high-end that defines classic Jazz Bass tone. This bridge position pickup combines overwound coil design with 1/4" diameter pole pieces to produce powerful, genre-spanning bass tone with exceptional sustain and sonic complexity.
Product Overview
The Quarter Pound Jazz Bass bridge pickup achieves its commanding presence through innovative 1/4" diameter Alnico 5 rod magnets that provide substantially increased magnetic field strength compared to standard Jazz Bass pole pieces. This enlarged magnetic structure captures more string vibration information, resulting in fuller, more even response across all four strings with enhanced sustain and harmonic complexity that translates through any amplifier or recording chain.
The hot coil winding delivers higher output than vintage-spec Jazz Bass pickups without sacrificing the clarity and definition that make the Jazz Bass format indispensable for versatile bassists. This careful balance provides the aggressive attack needed for rock, punk, and metal while retaining sufficient articulation for funk, R&B, and jazz applications where note definition and dynamic response prove essential.
Hand-built in Seymour Duncan's Santa Barbara, California facility, each pickup receives individual attention during assembly using premium Alnico 5 rod magnets and Forbon flatwork materials. Wax potting eliminates microphonic squealing for reliable performance at high stage volumes. The pickup drops directly into American Standard Jazz Bass routing, providing straightforward installation for players upgrading from factory pickups.

- Rock and punk bassists requiring aggressive output and commanding presence in dense band mixes
- Versatile players needing both high-output punch and articulate fingerstyle clarity from one instrument
- Session musicians demanding reliable tone across diverse musical genres and playing techniques
- Recording bassists seeking enhanced sustain and harmonic complexity for studio productions
- Upgrade-focused players enhancing American Standard Jazz Bass output and tonal authority
Key Features
Quarter-Inch Pole Pieces

This enlarged magnetic structure captures more string information for fuller response, extended sustain, and enhanced harmonic complexity that defines the Quarter Pound series' commanding presence.
Hot Coil Winding
