What string spacing does this pickup accommodate?

The AJB-5N accommodates string spacing up to 3.00 inches (76.2mm), making it compatible with most modern 5-string bass configurations.

Is this pickup suitable for styles outside jazz and fusion?

This pickup is optimized for jazz, fusion, studio sessions, and live performance contexts where articulate, focused tone is valued. It is not recommended for metal or punk styles that typically require different tonal characteristics.

What is included with this pickup?

The AJB-5N comes with a 3-conductor lead wire, a logo cover to protect the coil and maintain instrument aesthetics, and operates on a single 9-volt battery supply.

Does this active preamp introduce noise or hum?

No; the fully discrete, ultra-quiet preamp operates at low impedance on a single 9-volt supply, delivering a negligible noise floor and eliminating hum while preserving your instrument's natural character.

How does the blade pole piece design affect tone?

Blade pole pieces respond to string movement with greater clarity and speed than individual posts, combined with a ceramic bar magnet tuned to a 4.9 kHz resonant peak for articulate, punchy midrange that cuts through a mix.

Seymour Duncan AJB-5N Active 5-String Neck Pickup For Jazz Bass

The AJB-5N delivers the articulate, focused response essential for tracking and mixing modern active jazz bass. Hand-built in Santa Barbara, this neck pickup combines blade pole pieces with a ceramic bar magnet to capture the full dynamic range of fingerstyle and pick playing across a 5-string configuration. The fully discrete, ultra-quiet preamp operates on a single 9-volt supply, eliminating hum and noise while preserving the natural character of your instrument during recording and live session work.

Design & Build

Constructed with a ceramic bar magnet and blade pole pieces instead of individual posts, the AJB-5N responds to string movement with clarity and speed, translating to clean, detailed tracking. The 3-conductor lead wire integrates seamlessly into existing wiring schemes, and the included logo cover maintains the instrument's aesthetic while protecting the coil during studio sessions.

Tone & Recording Character

The fully discrete, 9-volt active preamp operates at low impedance and delivers excellent dynamic range with negligible noise floor—critical for capturing transparent recordings without unwanted artifacts. A resonant peak at 4.9 kHz and 13k DC resistance provide the articulation and punch essential for cutting through a mix in jazz, fusion, and modern bass contexts, ensuring your neck pickup tracks sit with clarity and definition alongside drums and keys.
