Dear Steve, Oversized tuning pins in a new piano is problematic in that there is no where to go from the fours. I have tuned a couple of pianos with 6/0 pins and found it very difficult. I would deminish the value of that piano because I don't know why such pins are in the piano. As regards cut pins, Yamaha has been using such pins for years and I have found them to be far more tunable than any other brand when I comes to pin control. I have had Yamahas in Broadway theatres that broke the same bass strings time after time. Those pins did not get loose dispite being turned out and in several times. When I was teaching full time the pianos in tuning rooms got tuned often eight hours a day, day after day with loose pins becoming a problem. Newton
