I have several hobbies I enjoy, however songs has been our core passion since I was a young child. Back then, I was just ecstatic to get our 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 good dark mahogany & others with alder & pine. I have a safe room to store them in, but 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 destruction that can alter the way it sounds & plays. If the environment is too dry, the wood will shrink & contract which can lead to numerous of the same results. In the end, you end up with drastic destruction that is often irreparable, so it’s best to control for humidity at all costs before your guitars beginning degrading. The magic number is somewhere around 50% depending on the make of your instrument. Someone I know mentioned the idea of putting a zone controlled Heating & Air Conditioning plan in our songs room, however since the air supply from our central AC was consistent & strong to that room, I couldn’t justify the expense of giving it a separate air conditioner altogether. My central goal was controlling for humidity after all, so this solution seemed enjoy overkill. Instead, I went out & purchased a small portable dehumidifier. It comes with its own humidity meter & can be set to maintain a area to a predetermined humidity level. I can set it right at 50% & know 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 chop corners on humidity control.
