Humidifier for Upright Bass

Description

If you're after one of those rubber thingies to hang in your bass to keep up the humidity, well here it is. It's a good quality unit, a perforated non-vinyl tube with a sponge material inside, with a disk on the end. You soak it in water, squeeze out the excess, wipe it off, and hang it inside though a f-hole.
But the question is... do you really need one? If you have a laminated (plywood) bass, probably not. Carved or hybrid (carved top), maybe.
Please see my FAQ on the topic, below, for more details on the need for and how to on humidification for your bass.
The soft, flexible tubing is just under ½” in diameter.
