The MusicNomad HONE patented humidity and temperature monitor is an accurate, reliable and easy-to-use method of monitoring your instrument’s environment. Ideal for acoustics, electrics and other string instruments, HONE will determine if you need a humidifier, dehumidifier or neither, and help protect your instrument from drying, warping, shrinking or cracking. The innovative design clips directly onto your guitar strings, and can also be placed in your case or any room you want to monitor.
