Monitoring and maintaining correct humidity levels for your bass can be a challenge. Many players don’t do anything, which seems to be the current trend.
However, if you are worried about it, here are two easy steps to ensure correct levels.
1. Buy a digital thermometer with a hygrometer from Radio Shack. These are accurate and inexpensive.
2. Rather than using Dampits which can actually drip and cause water damage, use a nasal mister! It delivers a fine mist which won’t damage the bass and is more useful anyway. 2 puffs a day when the humidity is below 40 percent is all you need.
