We spent 24 hours on research, videography, and editing, to review the top selections for this wiki. Separations, cracks, loose bridges or neck joints, changes in sound — these are only a handful of the misfortunes that could befall your beloved guitar in dry environments. But you can prevent these issues with a humidifier, which is designed to keep the air inside your instrument optimally moist. Many come with a hygrometer, too, a tool for measuring moisture in the air. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
