Oasis OH-21 Bass Humidifier
As with all of Oasis humidifiers, you can count on the OH-21 Bass Humidifier to protect your instrument and provide humidification without leaking. Due to the high humidity output of this humidifier, the unit should be refilled every two to three days.
- for ¾ size or full size double basses--bottom F hole opening must be at least 1 ¼”
- same size as other Oasis humidifiers, but provides substantially more daily humidity
- unique Oasis® design makes it easy to see when to refill
- 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 is knotted at the end and extends through two pieces of felt (user-installed). One 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 instrument. A 10 cc syringe is included.
- distilled water is recommended to extend the life of humidifier
