We highly recommend that guitar humidifiers be used with all instruments, particularly with acoustic guitars with solid tops or all solid construction. Guitars like a relative humidity of around 45%, which is hard to maintain in your home, even if you have a home humidifier or live in a more humid part of the world than us. Consequences of a dry guitar can range from altering the action and playability of the guitar to splits and cracks in the wood, and dryness is a problem that no manufacturer will provide warranty coverage for. So please, keep your purchase humidified, you can browse our selection of humidifiers here.
