Hi
,
Thanks for writing, I'm happy to set the record straight from Taylor's perspective.
Basically, leave guitars tuned to pitch. Detuning a guitar while not playing it is BAD for the guitar.
When you detune a guitar you decrease the tension on the neck and top. This allows the neck to backbow and the top to relax. The top relaxing isn't such a big deal but the back and forth of constantly detuning and retuning isn't ideal. Leaving the neck backbowed for extended periods of time can do harm. if the neck develops a "memory" of being backbowed, it may not have the relief that it should or did when it was new, causing a major problem.
We hear this question from all over Asia but in other parts of the world it has never been a topic of discussion. I believe the myth was started by people long ago who didn't understand the effects of humidity on acoustic guitars. Since many parts of Asia are extremely humid, a guitar left in natural conditions with high relative humidity (regularly over 60%RH, and often over 80%RH) will absorb excess moisture and the body will swell or blow up like a balloon. This is often misdiagnosed and though to be caused by the string tension pulling on the top, which is completely incorrect. Still, once someone thinks that's true, they tend to be the ones detuning all their guitars.
So, once again, keep them tuned! Control the humidity too.
There is no harm in changing all the strings at once and it's necessary if you plan to clean and condition the fretboard. Just don't leave it that way for days!
The worst thing that would happen is the neck might need a truss rod adjustment if it doesn't come back the the exact same spot after removing all the strings (and tension) and putting new strings on. This was also a precaution for guitars with an undersaddle pickup. Since those pickups are pressure sensitve, the saddle could shift and throw off the balance from string to string when playing amplified. Also not a huge deal but may require a tech to refit the saddle.
Hope this helps!
