Whether or not you live in an über-dry climate, humidity should always be front-of-mind when it comes to your prized instruments.

To help you accomplish this, we’ve rounded up some of the available options designed to prevent those splits and cracks nobody wants (except for work-hungry luthiers).


Two-Way Humidification System

No additional parts or replacement packets are needed for this humidifier that keeps your acoustic guitar at just the right humidity to preserve its wood. Simply immerse the humidifier in water, shake off excess, and then position it in a soundhole that measures between 3 3/4" and 4 1/8".

Super Guitar Humidifier
This easy-to-use system keeps the humidity level at an optimum 45-55 percent and the included monitor with number-indicator spots allow the user to take a relative-humidity percentage reading.
