Q: I want to make sure my guitars are kept at the proper humidity this winter. But I’m confused; am I better off to get an overall humidifier for the room or to get individual humidifiers for each guitar?
A: It is indeed important to keep guitars, especially sensitive acoustic guitars, in the proper 40-60% humidity range to prevent cracking, structural damage, and other problems. Ideally, your guitars are stored in their cases when you are not playing them, in which case a single-guitar humidifier for each instrument is a great solution. If you need to humidify a larger space, such as a room full of guitars, then a room humidifier may be a better choice.
