The LR Baggs M1 Active Acoustic Guitar Soundhole Pickup is one of the most natural-sounding and feedback-resistant magnetic soundhole pickups available. Unlike conventional magnetic pickups, it uses LR Baggs' patented body-sensitive design, where a suspended secondary coil captures top vibrations and body resonance for a rich, open acoustic tone with greater warmth, detail, and realism. A built-in audiophile-grade preamp delivers a strong, full-range signal directly to an acoustic amplifier, PA, or recording interface without needing an external preamp. With onboard volume control, adjustable pole pieces, and an included pre-wired strapjack harness, the M1 Active offers professional-quality amplified acoustic tone, ideal for both live performance and studio use. Features Patented body-sensitive humbucking design captures both string and soundboard resonance. Built-in high-quality preamp provides a powerful, plug-and-play signal. Highly feedback-resistant design suits dependable stage performance. Adjustable pole pieces ensure optimal balance across all strings. Includes a pre-wired strapjack harness for straightforward installation.
