I know you've studied = this a fair bit but I think after hearing Ron o. ,Ron, N. , Del, John Har= tman and others I believe there is enough evidence that the front duplex = being tuned is a detriment to sustain. The sympathetically vibrating stri= ng segment at the front duplex is largely responsible for drawing energy = from the vibrating segment ,reducing sustain/power and creating more buz= zing than pianists can tolerate. This segment would benefit greatly fom b= eing detuned. I've noticed than in Mason BB's from different era's the = front duplex went from being in a tuned configuration to on of equal leng= th string lengths in the front duplex. In the latter the tone is cleaner = with no buzzing and excellent sustain characteristics. As to the rear duplexes having a significant effect on tone ,at least = for me the jury is still out. If all other aspects of the pianos tone pro= ducing system are set up well the overall increase in performance to me = is not enhanced significantly. However as has been discussed at length on= list has been the detriment of too short of a back scale choking /restri= cting bridge movement thus tone quality ,power etc. Convince me otherwise= . I'm open minded. =20 Regards----Dale Erwin =20 ----- Original Message ----- From: Duplexdan@AOL.COM Sent: Thursday, October 25, 2001 11:45 PM To: pianotech@ptg.org Subject: Re: Voicing M&H BB =20 Voicing a M & H is not only to be construed by dealing with the hammers. = if the duplex scale is not tuned correctly, the tone can never achieve its maximum potential.
