All guitars are sensitive to changes in air humidity. Acoustic guitars are more sensitive to air humidity fluctuations than electric guitars.
Most metal string acoustic and electric guitars have a so-called “truss rod” in the neck, which can be used to adjust the bend of the neck. The necessary distance between the stings and the frets depends on what the player is accustomed to. The neck of a guitar bends closer to the strings in winter and further away in summer. We advise to have a specialist adjust the bend of the guitar neck.
The greatest problem in summer is excessively high air humidity.The body of an acoustic guitar may bend and the elevated bridge may make playing hard or more difficult. In this case, it is recommended to use a lower bridge.
Proper storage of a guitar is especially important in winter as the fine tuning will distort in improper storage conditions and, in the worst case, the instrument may become unusable. The central heating and hot-air blowers used in winter bring air humidity to an extremely low level.If a guitar with a solid wood soundboard is kept in too dry air, the soundboard will shrink. The soundboard will bend out of shape, the distance between the strings and the neck will decrease and the strings will be “chirruping” against the frets. The fingerboard will also dry and the ends of the frets will protrude. In an environment of especially dry air, the glued parts of a guitar will tear, the lacquer layer will crack and, in the worst case, cracks may appear in the guitar.
