I had been told by one of an experience guitar player I shall not remove all guitar strings at once. I should remove one string at a time and replace each as I go. The reason is by removing all strings at once, I will affect the tension and create harm to the guitar neck. Is it true?
Yes, I heard about this as well but personally I do not agree with it because there’s no documented negative effect of removing all strings. I don’t think doing this will damage your guitar neck.
I always remove all strings from the guitar so that I could easily clean and wipe down the fingerboard with micro fiber, follow by putting on the new set. This had actually save lot of my time and effort.
