Ray, in reply to the part of your query dealing with rendering problems, I have used Protek CLP with good success in most instances of excess friction in the capo section. I find that most of the friction comes from the area where the strings ride up over the felt. CLP makes it easier to tune, and reduces string breakage while tuning, but I have to reapply about every other tuning on problem pianos. We do have a 1984 S&S D that, in the high tenor section (up to C#5), even the CLP is insufficient help. My boss says impact tuning helps stabilize that section, even though it is still difficult. I've wondered myself about pianos that always pop. It seems I see them more in spaces with wide humidity swings, for what that's worth. Looking forward to more postings on this topic. ---------------------------------- Lawrence Becker, RPT College-Conservatory of Music University of Cincinnati ----------------------------------
