Seymour Duncan SJ5-3B Quarter Pound 5-String Bridge Pickup For Jazz Bass

The SJ5-3B Quarter Pound delivers the focused, articulate voice jazz bassists demand, with a high-output true single-coil design that cuts through the mix without sacrificing definition. Its over-wound coil and Alnico 5 magnets produce a punchy, present tone ideal for tight ensemble playing and recorded work. Direct-retrofit compatibility with Fender Jazz V basses makes installation straightforward for players ready to upgrade their bridge position.

Tone & Output Character

The 22.2 kΩ DC resistance and 5.56 kHz resonant peak combine to deliver strong output with natural presence in the upper midrange, perfect for cutting through dense arrangements. The 7/3/6 EQ curve (Bass/Mid/Treble) emphasizes low-end weight and treble clarity while keeping the midrange controlled, yielding a balanced yet assertive jazz tone.

Construction & Compatibility

Wax potting eliminates microphonic squeal and feedback under heavy playing dynamics, while Alnico 5 rod magnets and Forbon flatwork ensure consistent magnetic field and durability. The pickup accommodates string spacings up to 3.10" (78.7mm), making it a direct fit for 5-string Jazz basses and other instruments with standard bridge spacing.
