You probably already know that your instrument can crack in dry weather. Repairing a cracked top of a fine guitar is both expensive and can alter the sound of your instrument. To solve this problem, guitarists have been using "sound hole" humidifiers since the 1960's.

 

Like other "sound hole" humidifiers, Oasis® fits between the strings of your instrument. The materials that touch your strings are relatively soft and will not scratch your strings. A blue polyurethane stabilizing bar fits over the neck of the humidifier. Once positioned in the sound hole, the stabilizing bar lies across the guitar strings to ensure even weight distribution. Oasis® never touches the body of your instrument.

 

The body of Oasis® is made from a specially designed fabric that allows water vapor (but not water) to pass through it. As the vapor transmission takes place, a vacuum is created and Oasis® shrinks to compensate for the loss of water. By watching the Oasis® shrink, you can determine when it is ready for refill. When refilling, you don't have to guess when it is full. Simply unscrew the black cap, fill with water to the top of the container and replace the cap. Once sealed, the water tight container is your first line of defense against leaks. Humigel™, the super absorbent polymer crystals inside Oasis™, are your second line of defense. Humigel™ captures up to 500 times its weight in water in an absorbent gel matrix.
