Seymour Duncan SA-3HC Woody Hum Canceling Acoustic Guitar Soundhole Pickup

The Seymour Duncan SA-3HC Woody delivers hum–canceling acoustic guitar amplification in a compact soundhole mount. Designed for steel–string acoustics, this passive magnetic pickup uses a stacked humbucker configuration to eliminate the hum and interference that plague single–coil designs. The unit fits standard soundholes and requires no modification or permanent installation, making it a practical choice for players who need amplified tone without drilling into their instrument.

The SA-3HC uses a dual–coil stacked humbucker with adjustable pole pieces to balance string–to–string output across the fretboard. Its passive design requires no battery or onboard power, drawing signal directly from string vibration over the magnetic field. The pickup connects via a shielded output cable terminated in a standard 6.35mm jack, ready for any amplifier or direct box input. Pole piece adjustment allows compensation for uneven string volumes, particularly useful when switching between different string gauges or correcting neck radius variations.
