D'Addario GHP Acoustic Guitar Humidifier Pro

The D'Addario Humidifier Pro maintains the condition of acoustic guitars even under extreme conditions. A special sponge, which stores 12 times its dry weight in water, significantly extends the maintenance periods and increases the degree of humidification in dry environments. This makes it much easier to
protect
your instrument against shrinkage of the wood, warping of the neck and cracks in the
body
.
In addition, the original playability of the instrument remains longer.

The Humidifier is simply hooked into the strings and then slowly and evenly distributes the moisture within the instrument without touching the wood. The only maintenance is to re-water the sponge from time to time. The new lid allows you to check the water level without removing the Humidifier Pro from the instrument.
