Keep your acoustic guitar's wood healthy with the RDM Guitar Humitron. Made from custom extruded resin, the Humitron is soft enough to exert pressure around the sound holes yet sufficiently sturdy to minimize contact with the instrument itself. When the humidity falls below 50% use the Humitron to keep the wood in your guitar from getting excessively dry. The Humitron uses water-suction stems which can absorb ten times their weight in water and then release it slowly through the holes.
