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.
