HH Combo Guitar Humidifier and Hygrometer
Additional Photos:
The OH-30 Offers a single unit humidifier & hygrometer combination.
The Oasis HH Combo is the only humidifier/hygrometer designed to fit in the soundhole of a steel string acoustic guitar. When using a humidifier to boost the humidity inside a musical instrument it is important to monitor humidity levels. Otherwise, maintaining correct humidity is just guesswork. The HH Combo has two parts. Above the strings, the upper portion of the unit contains a clearly visible and accurate hygrometer, which can be calibrated by the user if necessary. The humidifier clips securely into the bottom of the hygrometer. Suspended by the strings, the humidifier releases moisture evenly and slowly inside the guitar yet never touches the instrument body. A specialized, drip resistant, sponge holds 10 times its dry weight in water, which allows for a longer periods between refills. There are four openings on each side of the humidifier for the water vapor to escape. This is sufficient for most dry areas. In dryer climates like Arizona, there are 4 additional openings which can be punched out to provide more humidity. The sponge is easily recharged by moistening the sponge with distilled water. Using the HH Combo during dry months will protect your instrument safe from cracks and warping.

Short of an auto-controlled humidity cabinet, this is probably the best way to protect your acoustic in dry climates. I weatherstripped my case to keep it from leaking too much air (it still breathes a little), and a charge of distilled water in this lasts a couple/few weeks. Ambient humidity can drop to under 10% here indoors in winter, and I don’t bring it up to much more than 20% with the house humidifier to avoid too much window condensation. The built-in hygrometer is very helpful combined with keeping an eye on what the guitar is doing. I have a ‘91 Larrivee with a nitro finish that’s pretty sensitive to humidity changes, and this has helped me keep it in good shape and sounding beautiful with a lot less fuss. The sponge takes longer to absorb water than it used to, but It looks like refills are available from Oasis.
