I've had a lot of P22's break bass strings. Specifically A1 (string #13). I spliced two of them (not easy to do since there is only about 1 inch between the top speaking termination point and the tuning pin.) And I think a year or two later the splices broke. I figured it was the severe angle of the string coming off the coil. On some I've seen the string overlapping the coil. It makes me cringe every time I tune that note on any P22 When replacing the strings, turn out the tuning pin enough so the coil is high enough that overlapping doesn't happen. It might mean that the pin can flagpole, but if we're talking bottom octave on a practice room piano, it's not a big deal. I used to find a lot of Yamaha P202's would break bass strings up by the tenor break. In those cases I thought that was a scaling problem.

It's interesting how you guys are nailing this on the head. I appreciate the help! More for me to explain to the customer than anything.

Is it a very short distance from termination to pin? Like this picture? If so, it's most likely the abrupt angle changes. I've also had a similar break in a very new YC console. Any ideas out there for avoiding breakage on strings like this?

I use CyberTuner, and the note was almost in tune, just a tiny bit flat, and as I turned the pin only one notch with my hammer to bring the note slightly above pitch so I could settle it back to pitch, the string snapped. Is there any rhyme or reason why a string breakage such as this would occur?
