The ¾ size double bass humidifier is the latest addition (2011) to Oasis' humidifier line up. It is the same size as our other humidifiers, but generates a great deal more daily humidity. Because of the large air capacity of the double bass, two humidifiers are generally needed to supply sufficient humidity. Due to the high humidity output, the unit needs to be refilled every three days.

The humidifiers fit inside the double bass through the hole at the bottom of the F hole. This humidifier will not fit in every double bass. The opening must be 1 ¼” or larger. This eliminates ½ size or smaller double basses but will fit most ¾ size double basses.

The suspension system is completely new. An elastic cord slips over the neck of the humidifier and is held in place by both tension and the humidifier cap. The cord extends through 2 pieces of felt (user installed) and is knotted at the end. Once piece of felt is round and fits in the F hole. The other is rectangular and fits outside the double bass keeping the humidifier from falling into the bass. Like all of Oasis' humidifiers, it is important to only use distilled water. Tap/bottled water have significant quantities of dissolved minerals that will eventually clog the liner, shortening the useful life of the humidifier.
