What size soundhole does this pickup fit?

The Active Mag Pickup mounts directly into soundholes between 3.75 and 4.2 inches in diameter with no modification required. Measure your soundhole before ordering to confirm compatibility.

How long do the batteries last?

Two CR2032 batteries are mounted directly to the pickup and deliver 160 hours of continuous operation per battery set. Batteries are easy to replace on the unit itself.

Can I use this pickup with my standard cables and amp?

Yes—the pickup has standard guitar cable connectivity and 1.0 K output impedance, making it compatible with any guitar amp, interface, or mixing rig without impedance matching concerns.

What makes this pickup good for live performance?

The hum-canceling magnetic design eliminates feedback and line-noise interference, while adjustable pole pieces per string ensure balanced output across your instrument. Integrated volume and tone controls let you shape your tone on stage without external pedals or preamps.

Does this require any guitar modification to install?

No—the pickup mounts directly into your soundhole between 3.75 and 4.2 inches in diameter with zero modification to the instrument.
