I was adjusting it, and my muscles go carried away. And, I went way to far way to fast. It wasn't till I was researching how to replace it that I found out you're supposed to turn it a quarter rotation per day. I went like 3 rotations in an hour! I am fifteen and learn by trial and error, so now I have to learn how to fix it! Hopefully minus the error part. It is broken a tiny ways below the nut. I may have been able to remove some wood and fix it that way, but now I have it apart so I might as well replace it.
