The strings on the 5th and 4th saddle of my guitar's whammy bar keep on snapping-out. I think the string lock inserts might have notches or loose. But still i don't what the real problem is. I don't know how to fix this. Guys i need your help.
Are you sure they're snapping and not just coming out because they're not held in properly? If they are breaking it sounds like you might need some new parts unless you can get in with some fine sand paper and smooth out the edges.
