Oasis OH-1 Guitar Humidifier
Humigel crystals hold humidity and prevent spills, while the Oasis humidifier is suspended into your guitar by its strings. Oasis also offers Humigel humidifiers that work in your case, or create greater humidity for low-humidity climates.
➤ We strongly recommend humidifiers, especially during the winter months, when central heating systems can easily cause indoor humidity to drop below 20%. According to Jeff the Repair Guru, you should use a humidifier, “… from the time you turn on your heat until you shut it down in the Spring.”
