I wonder if anyone can help me here. I bought a used guitar from Ebay and it looked fine at first sight. The action needed adjusting and I tune to Eb so I decided to adjust the truss-rod. I turned it clockwise a couple of times and it felt like it came loose so I thought, "Well, the Truss-Rod is broken". And I can't adjust this guitar :o/
I then looked at the neck and I could see a crack right behind the locking nut.
I really don't think it could have been me as I didn't turn the rod tight of nothing like that but I wanted to check if it's possible to crack a neck by adjusting the truss-rod.
Here's a picture of the damage:
Hope someone can help.
