Operating on the properties of a humbucker's lower coil to cancel out hum and enhance tone in electrified scenarios, the LR Baggs M1A Active Soundhole Pickup delivers high-fidelity tone from your favorite acoustic when you need to plug in. Adjustable pole pieces let you tailor the M1A to the exact specs of your guitar, and a built-in volume control lets you keep control whether it's a coffee shop show or outdoor stage.
