I have several hobbies I enjoy, however music has been my core passion since I was a young child. Back then, I was just ecstatic to get my hands on a cheap starter guitar from a department store to pluck away at aimlessly. I would have salivated at the thought of owning some of the amazing acoustic guitars I own today. Some of them are made with attractive dark mahogany & others with alder & pine. I have a safe room to store them in, although I can’t figure out how to maintain the humidity in there to protect the guitars. Too much moisture & the wood will swell & crack, leaving considerable structural disfigure that can alter the way it sounds & plays. If the environment is too dry, the wood will shrink & contract which can lead to more than 2 of the same results. In the end, you end up with severe disfigure that is often irreparable, so it’s best to control for humidity at all costs before your guitars start degrading. The magic number is anywhere around 50% depending on the make of your instrument. Someone I think mentioned the plan of putting a zone controlled HVAC method in my music room, however since the air supply from my central A/C was consistent & strong to that room, I couldn’t justify the expense of giving it a separate a/c altogether. My central goal was controlling for humidity after all, so this solution seemed appreciate overkill. Instead, I went out & purchased a small portable dehumidifier. It comes with its own humidity meter & can be set to maintain a section to a predetermined humidity level. I can set it right at 50% & think that the room will not get too wet or get too dry. When you’re protecting instruments that cost over $1,000 a piece, you can’t afford to cut corners on humidity control.
