But it can still happen, even if it hasn’t happened to you yet. I’m sure some will or have posted their experiences with this. It has happened to me before. Wilkinson bridge that has a pin the ball end of the string is attached to. If you don’t take care to let the string untwist in your fingers as you bring it up to the headstock before you put it in the tuner it can happen. Can still happen on a standard bridge if you put too much tension on the ball end of the string as you string it up.Some people claim string issues can do this...twisted or defective. I have never experienced that.
I have never seen the effects of atomic radiation personally either, but it doesn’t mean it doesn’t exist.
