Seymour Duncan APJ-1 Pro Active For P-Bass Neck/Bridge Pickup

The set includes the neck and bridge pickups, a built-in active preamp, potentiometers, a 9V battery clip, an output jack, mounting screws, a wiring schematic, and all necessary components for drop-in installation.

The 9V battery provides approximately 2,000 continuous hours of battery life, which translates to several months of regular playing before replacement.

Yes—the APJ-1 is designed for drop-in installation with a 3-conductor lead wire that offers flexible wiring configurations, and the included schematic guides you through integration into existing bass electronics.

The active circuitry delivers a tighter, more articulate response with defined transients and punchy attack, along with a controlled low end that stays focused rather than boomy—ideal for funk and rock where clarity matters.

The APJ-1 excels in funk, rock, and modern studio and live settings where punchy articulation and headroom are priorities; it is less suited for folk and traditional jazz applications.
