Humidity is important. When I build a guitar in my shop, I try to control the humidity. The wood must by dry. I have three ways to change humidity. First is a dehumidifier. It gets used mostly in the summer, but rarely even then. I have a cool mist humidifier. I also have a heater. The heat lowers the humidity in the shop quite a bit.
But before you control it, you have to measure it. I have two moisture meters to measure the humidity in each piece of wood that I use. Both give similar readings but I have two to make sure that every piece of wood that I use is as dry as it can be before it goes into a guitar.
Humidity in the air is important when building instruments. I control it with a dehumidifier, or a humidifier when the relative humidity in the shop goes too far up or down. How can I tell?
I have a favorite hygrometer. Here are three. Notice that they all report the temperature as 68 degrees Fahrenheit. Relative humidity is another issue though. One reports 45%, another reports 33%, and another 38%. Yes. Different hygrometers give different readings. The numbers seem exact until you realize the validity is in doubt due to individuality of the devices.
