Care and Maintenance of an Acoustic Guitar
Treat your instrument with care-even when not playing it
Store in an environment with little variation in temperature and humidity
Acoustic guitars are susceptible to humidity and temperature. They should be stored in locations with a humidity of 45% to 55%, and must never be stored in dry or very hot/humid locations. Avoid storing them in locations where the temperature fluctuates, such as in direct sunlight or near the A/C.
Place it in its case when not playing
The tops of most modern guitars are created from a single panel. In other words, the top is formed from a single piece of pure wood. Although this provides for a nice sound, it also breaks more easily than plywood, which is formed from two panels. Be careful about showing off your favorite guitar on a stand-it would be a shame if it was struck and broken by a vacuum cleaner or the like during cleaning. It is better to place your precious guitar in its case.
Loosen the strings if you will not be playing for a while
Although this does not apply to those who play every day, those who play only whenever the mood strikes them should loosen the strings to keep the body in good shape. Otherwise, the tension of the strings could cause the bridge to lift off from the guitar. Be sure to do this to keep your instrument in good shape-a single turn of the tuning key is enough.
What if the bridge lifts off from the guitar?
If the strings of a guitar are kept tight for a long time, the back side of the bridge could swell, or the entire bridge itself could start to lift off from the guitar. The guitar can often still be played by lowering the strings if the bridge is only slightly swollen. However, if the bridge has started to lift from the guitar it will need to be repaired before installing new strings. In this case, never install strings without having the instrument repaired, as the bridge could even separate from the guitar! Please consult a specialist if you need to have a lifted bridge repaired.
