OUCH,
Snapping strings do have a freak out factor! The coil in the hand - my bass has done that a couple of times
Floating also on banjo, mandolin, cello, violin, my two lovely Bruno Royal Artists & my Emperador semi acoustic bass but not my Epi Sheraton though as it's a log with hollow wings.
Lucky the ol' jonah doens't have a floater - imagine snapping a string inside that!
Here's an idiot move for you (being taht I AM an idiot) - I was using a little string winder to take up the slack when re stringing a nylon acoustic - wasn't paying attention and wound the button/knob off. Cursed myself with the task of repairing that later & proceeded to the next string - became distracted & whamo - did it again.
Now I've had that guitar & a new set of machines waiting to be done for three years - I'm too embarrassed by it to even look at it.
