biskuuthe301stspartanIf you play guitar you would know that strings can get detuned even within an hour and sometimes even less. I've had strings get detuned as I'm playing a live. Not much, just around a semitone, but its still noticeable by ear.biskuuthe strings being detuned is, rather obviously, an indicator for the air having some potentially harmful effect on the guitar.tambothat doesn't make any sense, that would be the case only if the string got more tense to the point of damaging/curving the neckbiskuuwhy does it matter, do you not tune your guitar every time you grab it to play?it matters because the wood can eventually crack or warp irreparably if the temp/humidity is too high.
if we are talking humidity then yes it affects the instrument, but the strings being detuned has nothing to do with damage
if you are concerned about warm environments damaging your guitar you shouldn't worry, i would however make sure that the instrument has a fresh varnish which you can get from a luthier very cheap (had ones for $30-40)
Guitar strings get detuned constantly thats why most good guitarists will tune every time they grab their guitar.
I do know that, I was just pointing out what the strings being detuned "has to do" with damage.
