No, Matt, the difference is definitely audible. It makes a startling difference. I've only tuned one GH1 WITH the change to 6 unisons of wound bichords, but the difference is night and day. It's actually tunable! dave David M.

I did suggest the usual voicing, fine tuning, etc. and he said that he has already had stuff done by other techs. He has done some research of his own on the Internet and has decided that he is is interested in the rescaling. I have not done any rescaling personally but I understand that most or all of the string parameters are entered into a computer program which then spits out recommendations for changing string diameters here and there and changing some plain trichords at the tenor to wound bichords. Then the physical work involves maybe drilling hitch pin holes, modifying the bridge, etc. I read in the archive that Yamaha used to offer a kit for these pianos but it was recommended by list contributors to do a custom scale for each piano for various reasons. So, my questions: 1) What is the best software to use to do the rescale? Or, does anyone out there accept parameters and run them through their own software as a service? 2) When all is said and done, is it possible that the difference in harmonicity may not even be audible? Thanks, -Matt _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives
