<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top" style="font: inherit;"><div>Ron,<br /> I'm quite an experienced (and muscular ragtime/stride) pianist, and yet I found this "bobbling" hammer problem on one of the brand-new, large, Yammy uprights I serviced at a local church. I do not remember the remedy I effected at this time, and vaguely remember that it was not what one would expect; but am not convinced that the problem was due to the pianist's "attack". I do, though, vaguely remember mentioning it on this list, and after deducing and effecting a solution, providing details.

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

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.
