Once I decided to put on his acoustic guitar strings electric from the tension of the tailpiece cracked. This was because the new strings had not cylindrical, and conical head. Buried in the openings of the head split the tree. Helped me an ordinary pushpin — they make great washers under head of strings. Had is that they break off the spikes and bend the cap along the profile groove.
