List friends and fiends, I have to say that I also NEVER break strings while tuning!!! When that recent thread was playing out I was too deep inside of bulk tuning to jump in. I decided to run an experiment to see if my statement above was true. In the last three days I have tuned 14 practice room consoles in preparation for the start of second semester next Wednesday. These beasties get tuned before each semester and again in the late spring before summer camps and vacation (mine). So... - mixture of Baldwin 243 and 242, Yamaha 202 and P2E. - all had been tuned to A440Hz in late August at an ambient relative humidity averaging 60%. - the humidity (indoors) this week has averaged 20% (high today outside, a balmy -4°F). - all had slipped into the 434-436Hz range for A4. - none have any humidity control systems in them... duh... I used my RCT in standard pitch raise mode and watched the ¢ overpull. - all got into the 16-18¢ overpull range going into the top octave. As luck would have it, _one_ string broke. I did not break it. It was that string's time to go. I merely assisted. D#7 (#79) 14 ga on a Baldwin 243 broke before getting up to pitch, let alone any overpull. I put in a new string and "prestretched" or "accelerated stretched" it to 100¢ sharp. [now, two days later it is down to about 25¢ sharp.] So... since, even in a pitchraise, I am unlikely to exceed 20% overpull and I can overpull a new string up 100¢ without breaking, I REFUSE to take the blame for breaking a string which is not even up to pitch.
