When properly used, a Dampit is an effective tool. It's too small to keep your instrument humidified in a large room...but it is perfect for the small environment created when your bass is in the case! If you are at school, or in a situation where you cannot control the humidity of the room your instrument is being stored in, or just want to keep it humidified on your way to a gig or rehearsal, a properly used Dampit will help to keep a micro-environment inside your bass case. Just be sure to follow these steps to make sure you are not causing more troubles than you are trying to protect.
