Will this pickup fit my five-string jazz bass?

The AJB-5B is designed specifically for five-string jazz basses and accommodates string spacing up to 3.10 inches (78.7mm), which meets modern jazz bass bridge spacing standards. The blade pole pieces also maintain compatibility with four-string instruments if needed. Check your bass's bridge spacing against this specification before ordering.

What kind of tone should I expect?

This pickup delivers a focused midrange response with excellent articulation and string definition across all five strings, making it ideal for jazz, fusion, and studio session work. The ceramic magnet and blade pole piece design provide transparent, controlled output that captures fingerstyle nuance without adding noise or coloration, and the fully discrete 9-volt preamp preserves dynamic range.

Is the active preamp difficult to install?

The pickup includes a 3-conductor lead wire for flexible wiring integration, and comes with all necessary mounting hardware (screws and springs). Installation requires basic soldering skills and familiarity with active electronics; the discrete preamp requires a 9-volt battery in your bass to operate.

Why is vacuum wax potting important?

Vacuum wax potting eliminates microphonic feedback and squeal, ensuring clean, noise-free performance in both studio tracking and live environments. This is especially critical for active pickups, which can be more susceptible to feedback if not properly shielded.

What's included in the package?

The AJB-5B ships with the pickup itself, a black cover, mounting screws, springs, and a 3-conductor lead wire ready for installation. No battery is included; you will need to supply a 9-volt battery to power the active preamp.
