D'Addario Humidipak Automatic Humidity Control System for Guitar

Your acoustic guitar is made from natural wood that constantly reacts to changes in humidity. Too little moisture can cause cracks, shrinking, sharp fret ends, and poor playability. Too much moisture can lead to swelling, high action, and long-term structural damage.

The D'Addario Humidipak Automatic Humidity Control System takes the guesswork out of guitar care by automatically maintaining the ideal humidity level inside your instrument. Using Boveda's patented two-way humidity control technology, the Humidipak system both adds and removes moisture as needed, helping keep your guitar at approximately 45–50% relative humidity without any monitoring or refilling.

Simply place the packs inside your guitar using the included soft pouch system and let Humidipak do the rest. It's one of the easiest and most effective ways to protect your investment year-round.
