L.R. Baggs M1A Pickup för akustisk gitarr

Stage-Ready Acoustic Tone from a Soundhole Pickup

The L.R. Baggs M1 Activ Soundhole Pickup is an active magnetic pickup that brings natural acoustic tone to the stage without permanently modifying the instrument. It clamps into the soundhole with two screws per side, leaving the guitar otherwise untouched. Inside, a stacked humbucker pairs a string-sensing coil with a second coil internally suspended to capture soundboard vibrations.

What Sets the M1 Activ Apart

Defining the character of the pickup is the suspended second coil, which picks up soundboard vibrations alongside the string signal — mimicking a soundboard transducer without the feedback risk. The active circuit runs on a single CR2032 button cell delivering more than 1,000 hours of runtime, while the integrated volume wheel lets the player trim level directly on the pickup.

Pickup Architecture and Signal Character

A stacked humbucker layout places the two coils one above the other, narrowing the footprint so less of the soundhole is blocked.

• Pickup Type: Active stacked humbucker
• The configuration utilizes two coils, with the second one internally suspended to add soundboard vibration response.
• Hum-cancelling, quiet operation for studio and stage

Power Supply and Onboard Controls

The active design requires a power source, but runtime is exceptional for a magnetic pickup.

• Battery: Single CR2032 button cell — 1,000+ hours of continuous playing time
• Volume Control: Built-in wheel on the housing
• Adjustable Pole Pieces: Six tunable poles with included allen wrench

Mounting, Jack, and Harness

Installation is reversible — the pickup clamps into the soundhole without altering the instrument.

• Onboard Jack: Gold-plated 1/8" jack
