Humidity, Temperature, and your Guitar


Changes in temperature and humidity levels are the leading cause of stringed instrument damage. From cracked finishes to neck resets, it behooves us to cover some vital information that will assist you in preventing such damage by providing a stable environment for your guitar. Keep in mind that these are only guidelines; some guitars are more sensitive than others. Older instruments may already have compromised necks and glue joints from past exposures and time, thus making them more vulnerable to damage.

Acceptable relative humidity levels for your guitar are around 40% - 60%. Relative humidity is the amount of moisture the air can hold at a given temperature. With regard to temperature, rapid temperature changes (20ºF or more per hour) should be avoided. Before introducing your guitar to any drastic environmental change, leave it in its case and allow time for temperatures to equalize. Even then, open the case only a crack and let the air come into contact with the instrument gradually before taking it out for play.

Low humidity is more damaging than high humidity. Especially at low humidity then, keep your guitar in its case when you aren't playing. It is much easier to maintain humidity in your case than the whole house. There are various humidifiers available, and I encourage you to do your research before picking any one. Of assistance also in monitoring the need for humidity or not is a lab quality thermometer. Choose one with an accuracy of +/- 5% or better.

An interesting product I encountered to assist with this issue is the ClimateCase cover. This cover provides a nearly air-tight, water-tight buffer between your guitar and the climate outside.The ClimateCase cover is designed as an insulated buffer between your guitar and the elements.

Protect your investment. Keep your guitar sounding and looking its best by making sure to maintain stable humidity levels and exercising caution when drastic temperature changes are encountered.

Finally, have your guitar regularly serviced so that any little problems that may pop up do not turn into costly repairs.
