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.

Seymour Duncan Active Mag Pickup

The Seymour Duncan Active Mag Pickup is a hum-canceling magnetic pickup engineered for capturing acoustic instrument signals with minimal modification to the source and maximum control at the point of capture. Its compact form factor mounts directly into soundholes between 3.75" and 4.2" in diameter, with on-body volume and tone controls that let you shape your tone during tracking without requiring external pedals or preamps—keeping your signal path direct and your tracking sessions efficient.

Design & Installation

This op-amp topology pickup uses two CR2032 batteries mounted directly to the unit, delivering 160 hours of continuous operation per battery set. The hum-canceling magnetic design with adjustable pole pieces per string ensures clean signal capture while allowing fine-tuned response for individual strings—critical for achieving balanced, articulate output across the instrument when tracking and mixing.

Audio Performance

The pickup delivers a 28.60 kHz frequency response with 0.0075% THD and an exceptionally low 89dBV noise floor, ensuring transparent, low-noise amplification through your recording chain. Its 1.0 K output impedance and 1.5mA current draw make it compatible with standard guitar cables and audio interfaces without impedance matching concerns, giving you reliable, predictable tracking performance.
