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

The SJB-3B Quarter Pound captures 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 during tracking and mixing, responding decisively to pick and finger techniques alike, making it essential for sessions where clarity and presence in bridge position define your recorded tone.

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 capturing slap, fingerstyle, and aggressive picking techniques across multiple takes. The EQ curve of 7/3/6 (Bass/Mid/Treble) provides defined low-end support without muddiness in the DAW, controlled midrange that won't overwhelm adjacent tracks, and bright treble articulation that translates clearly through any monitoring or playback chain.

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 across recording sessions. The wax-potted design eliminates feedback and squealing, ensuring stable operation under any gain staging or amplifier setting in the studio.
