D'Addario Acoustic Guitar Humidifier Pro

Protect your acoustic guitar from cracking, warping, and tonal degradation with the D’Addario Acoustic Guitar Humidifier Pro—a simple, effective, and affordable solution for maintaining ideal humidity levels. Designed to suspend safely in your instrument’s soundhole, this innovative humidifier keeps moisture away from your guitar’s body and finish while delivering essential humidity directly where it’s needed most.
