If it’s breaking right under the tuning pin I’d check first for sharp edges or burrs on the tuning pin itself, especially around the hole the string goes through.

Definitely call Dusty. And check everything that can come into contact with the string in that general area. It may be hard to tell exactly where the break happened since the string is stretched out when tuned up but things shift when it goes slack after it breaks.

So check the tuning pin itself, but also the bridge pin, and check the lever. Even though the strings may not have broken while the levers were engaged if the levers have a rough edge to them they could we wearing and weakening the string enough that they eventually just break from the tension on them.

Look very closely, and use your hands and your eyes because this kind of thing can be hard or impossible to just see with your eyes. I had a string that kept breaking at the soundboard right at the sound hole. It took two new strings breaking before I noticed that the metal grommet set in the string hole was broken and creating a sharp edge that was cutting the string. I had to get right up to it to see it and when I ran my finger along it I felt it immediately, but from any distance it was invisible, even when I was changing the string I didn’t see it because I wasn’t looking for it.

Hi Leah, I have string breaking troubles too.

Oh, oof, apparently I need to pay more attention! I see you stated they broke just under the tuning pin. Check for a rough edge around the hole in the pin. Also, be sure that the string is centered on the guide pin, and in line with the tuning pin.
