I was playing my jackson warrior when the B string came out of the bridge. It was unbroken so I took off the nut loosened it and put it back and made sure it was reaaaallllllyyyy tight figurely it must have come lose or something. A minute later when I was bending that string it happened agian..... Is it the string or the bridge, or something else??? This has never happened before btw

This happened to my friend depending on the FR it could be the knife-edge as my friend changed his and it fixed it.
