I remember a class with Chris Robinson once demonstrating the effect re-pinning has on voicing. I believe he used a spectrum analyzer to demonstrate the harmonics before and after re-pinning. Very convincing! Will the Reyburn CyberTuner mini spectrum analyzer show these differences? I have one on order, so I'll soon find out! : ) John Minor University of Illinois --------------------------------------------- I have been having some interesting time with our Hamburg Steinway here at Stanford. This is 9 years old. I filed the hammers for the first time...I know, not heavy playing...but I repinned for the 2nd time in a year. Went from 4 grams to 2 grams or so...I decided to repin at 5 to 6 grams. The tone is projecting (tone above the strings) to beat the band...the combination of careful filing and repinning has, imho, brought the piano back to it's new piano sound...I'd appreciate comment on center pinning/tone and concert instruments...
