[pianotech] Yamaha Uprights

No, there isn't. In the Yamahas I spoke of, contact of the jack tail to 
the letoff button can, unless it's changed in the last five or so years, 
be clearly felt as an increased resistance. This is after the damper has 
lifted, and in a piano in good regulation.

Ron--I find that part you cite as less objectionable once the damper spring tension is lessened.

My experience has been that experienced pianists don't have this 
problem. It's the kids and beginners.
