Product Overview
The D'Addario GHP Humidifier Pro is designed to protect acoustic guitars from the damaging effects of dry air, including cracks, warped necks, and shrinkage. Featuring a specialized hydrophilic sponge that holds twelve times its dry weight in water (significantly more than ordinary sponges), it releases moisture evenly and slowly inside the guitar body while suspended by the strings, ensuring it never contacts the guitar’s finish. The humidifier's stopper lets you check the moisture status without removal, providing a tight seal to maintain ideal humidity levels and prolonging the instrument’s playability and lifespan.
