People say use them, people say don't use them... people...anyway...after reading the post on the 2x list, I quit using them but recently noticed that the principal bassist for the KC Symphony uses a couple. I currently have a home humidifier as well as a room humidifier (bass room). I don't measure the h levels but I use the rule of thumb "if I'm comfortable-the bass is comfortable" and my skin is very sensitive to dryness. So.....do dampits work, should I use them only for travel, should I not use them at all? I am concerned because my brand new bass has already cracked.
