Humitron humidifier for double bass

Excessively dry air is the enemy of every stringed instrument. Especially in winter, central heating systems cause the humidity to drop, which quickly leads to stress cracks. The Humitron humidifier helps to keep the climate in the double bass under control. Application: Soak the humidifier in water, squeeze excess water out of the sponge, wipe dry and hang it in the bass through a ƒ-hole.
