Maintaining your instruments humidity level is essential to preserve its playability, sound and integrity. The humidifier releases moisture evenly and slowly inside your instruments case to maintain the proper humidity level preventing cracks, warping, and shrinkage to your instrument. Using the humidifier is as easy as moistening the sponge when it becomes dry. The small instrument humidifier can also be used in conjunction with the Planet Waves Soundhole humidifier (GH) for acoustic guitar cases when your humidity is consistently 20% or lower.
