The Planet Waves Acoustic Guitar Humidifier with HTS has an open-cell phenolic foam insert that slowly releases moisture and doesn't shrink or deform to cause leakage. Registers humidity levels from 20%-99% and temperature. Memory function records date and time of the highest and lowest temperature and humidity levels. The Planet Waves Acoustic Guitar Humidifier suspends from strings so that it doesn't actually touch your guitar.
