The Humitron humidifier stores inside your guitar, mandolin or violin-family instrument to prevent damage from low humidity. The Humitron works much like the Dampit brand, but it does not offer a sound hole cover—which does allow moisture to evaporate more quickly than a Dampit. That’s not a big problem, but you will need to be aware and re-soak the tube more often.
➤ 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.”
