Seymour Duncan SJB-3B Quarter Pound 4-String Bridge Pickup For Jazz Bass

The SJB-3B Quarter Pound delivers aggressive, punchy output with the articulate character that defines Seymour Duncan's Jazz Bass pickup line. This high-output single-coil design cuts through dense mixes and responds decisively to pick and finger techniques alike, making it the choice for players who demand clarity and presence in bridge position.

Tone & Output Character

The 14.61 kΩ DC resistance and 3.9 kHz resonant peak create a midrange-focused response with substantial treble presence, ideal for slap, fingerstyle, and aggressive picking techniques. The EQ curve of 7/3/6 (Bass/Mid/Treble) provides defined low-end support without muddiness, controlled midrange that won't overwhelm, and bright treble articulation that cuts through any band context.

Construction & Reliability

Hand-built in Santa Barbara, CA, this pickup uses Alnico 5 rod magnets and Forbon flatwork paired with a single conductor PVC cable for durability and consistent performance on any stage or studio session. The wax-potted design eliminates feedback and squealing, ensuring stable operation under any playing condition or amplifier setting—essential for bassists who gig regularly.
