What does RWRP winding mean, and why does it matter?

RWRP (reverse wound/reverse polarity) means this neck pickup is wound in the opposite direction and phase from a standard bridge pickup, so they cancel hum when used together—a critical feature for live performance and studio work where electromagnetic interference can be problematic.

Is this pickup suitable for genres other than jazz?

This pickup is engineered specifically for jazz, studio sessions, and live performance; it is not designed for metal or djent styles, where higher output and different tonal characteristics are needed.

What output level does this pickup have, and will it match my bridge pickup?

The SJB-3N has a DC resistance of 13.30k ohms, delivering moderate, balanced output ideal for jazz contexts; pair it with a standard Seymour Duncan bridge jazz pickup for seamless hum cancellation and tonal cohesion across your bass.

What magnets and construction methods are used in this pickup?

This pickup uses Alnico 5 rod magnets (1/4" diameter) for warmth and harmonic complexity, combined with wax-potted construction and Forbon flatwork to ensure mechanical stability and consistent tone during performance and recording.

What is included with this pickup?

The pickup ships with a black pickup cover and chrome screws, ready for installation into your four-string jazz bass.

Seymour Duncan SJB-3N Quarter Pound 4-String Neck Pickup For Jazz Bass

The Seymour Duncan SJB-3N Quarter Pound delivers the warm, articulate midrange character essential to capturing authentic jazz bass tones in the studio, with a controlled output that sits naturally in a mix without overwhelming your recording chain. This neck pickup is engineered specifically for four-string jazz bass applications, offering the sonic clarity and definition that producers and engineers rely on for session-ready performances. Hand-built in Santa Barbara, this pickup combines traditional craftsmanship with proven Seymour Duncan design principles.

Tone & Output Character

The 13.30k ohms DC resistance yields a moderate, balanced output ideal for jazz recording contexts—articulate enough to define note separation in chord work during tracking, yet controlled enough to blend seamlessly with bridge pickup combinations in the mix. Alnico 5 rod magnets (1/4" diameter) deliver the warmth and harmonic complexity that define the jazz bass sound, avoiding the harsh peaks that can muddy ensemble recordings.

Construction & Design

Built with a single-coil configuration and RWRP (reverse wound/reverse polarity) winding, this pickup cancels hum when paired with a standard-wound bridge pickup—a critical feature for clean studio recordings and session work. Wax-potted construction ensures mechanical stability and tonal consistency across multiple takes, while the Forbon flatwork and PVC lead wire provide durability and reliable signal transmission to your interface or preamp.
