I've had to remove the strings many times in the last week for different reasons (truss rod, electrical short, PU broken) and what has happened is the cotton? binding on the end of two strings has come of leaving the winding at the end of the string exposed. Where it's exposed dose actually wrap around the winding post and I've noticed that when I tune these strings there's like a creaking sound and feel in the machine head. Is this a problem? ie the winding will gouge-damage the winding post or someyhing else? Thank you.
