DESCRIPTION

If you love your J-bass but are tired of getting lost in a mix, then you definitely need to look into the Quarter Pound J pickup set. These super high-output passive pickups have a distinctly non-vintage character. They're full of mids and punch that cuts through even the densest arrangements.

All that punch and mids have made the Quarter Pounders the go-to choice for J pickups in heavier genres, since they have the ability to cut through a wall of distorted guitars. But their usefulness extends far beyond heavy music. Any situation where you need your bass to be heard clearly will benefit from the Quarter Pound's focused, aggressive character.

The design philosophy behind the Quarter Pound series focuses on maximum output and midrange presence. Seymour Duncan achieved this through larger pole pieces and a hotter wind that pushes these pickups well beyond traditional J-bass output levels. The result is a pickup that demands attention in any mix, whether you're playing clean or with effects.

The frequency response is carefully tuned to emphasize the midrange frequencies that help bass cut through complex arrangements. While vintage J pickups often get buried under layers of guitars and keyboards, the Quarter Pounds maintain their presence and clarity. The low end is tight and controlled, preventing muddiness, while the high end provides the attack and definition that modern playing demands.

The build quality reflects Seymour Duncan's decades of experience in pickup manufacturing. Each pickup is wound to exact specifications, ensuring consistency and reliability. The materials are selected for their sonic properties and long-term stability, while the assembly process maintains the tight tolerances that ensure optimal performance.

Whether you're playing metal, punk, hard rock, or any style that demands cutting power, the Quarter Pound J pickup set delivers the aggressive tone that has made these pickups a favorite among players who refuse to get lost in the mix. They represent a fundamental shift from vintage-style J pickups toward a punchier and assertive approach to J bass tone.

From Seymour Duncan

One of Seymour Duncan’s most popular bass models, the Quarter Pound for Jazz Bass¼ was designed to take your bass tone to new heights. This neck and bridge pickup set has it all: hot output, great attack and massive attitude. The 1/4” diameter pole pieces and hot coil windings deliver a full, even response with great sustain and complexity that are at home in any genre of music. The neck pickup is RW/RP (reverse wind reverse polarity) for hum cancellation when both pickups are used together. These pickups are a drop-in replacement for any American Standard Jazz Bass¼.

Hand built in Santa Barbara, CA the Quarter Pound for Jazz BassÂź uses Alnico 5 rod magnets and Forbon flatwork, and is wax potted for squeal-free operation. Comes with black cover.

WHAT IS THE TONE OF THE SEYMOUR DUNCAN SJB-3 QUARTER POUND JAZZ BASSÂź PICKUP SET?

The Duncan Quarter Pounder pickups are aggressive. The mids have plenty of heft that can help a bass feel more ‘forward’ in the mid of a band. While the low and top end are present, the mid range tend to power the overall vibe tonally.
