Guys, help me out, I have a mental block....... gonna change the strings on my MM SR5 and can't remember if I should change them one at a time or if it's OK to pull them all off before changing. I wanted to clean the fretboard is why I prefered them all off at once. I guess I'm worried about the need for string tension on the neck and or the possible harm of no tension with all strings removed. Guess my confusion is because I always change them one at a time......help please.........Bud
