MiSi Acoustic Trio Air Pickup for Guitar/Guitalele - Rechargeable Pickup - Battery Free

The MiSi Acoustic Air Trio pickup system is a thoughtfully engineered solution for players who want a natural, studio-like acoustic tone without the hassle of traditional electronics.

At its core, the MiSi Acoustic Air Trio combines an undersaddle piezo pickup—based on the well-regarded L.R. Baggs Element—with a discreet internal MEMS microphone, allowing it to capture both the direct string vibration and the airy resonance inside the guitar body. This dual-source design produces a tone that feels remarkably balanced, detailed, and true to the instrument’s natural voice, avoiding the harshness often associated with piezo-only systems. What truly sets it apart, however, is MiSi’s innovative battery-free active preamp, which uses a rechargeable capacitor instead of a conventional battery—simply plug in the charger for about a minute and enjoy hours of performance without worrying about replacements or power loss . The system also features subtle, soundhole-mounted controls for blending microphone and pickup signals, giving players intuitive control over warmth, clarity, and feedback resistance. Altogether, the MiSi Acoustic Air Trio stands out as a minimalist yet sophisticated pickup system that delivers professional-grade amplified tone while maintaining the organic character of an acoustic guitar.

All you have to do is plug it in for 60 seconds using the Mi-Si Power Charger, providing you with up to 16 hours of performance time. 

*Installation is $55 and requires a 3-5 day window.
