If you=B9re describing what I think you=B9re describing, this is very common on many Asian actions....and it=B9s not felt-hardening, but something to do with the jack position being too far back, and the whippen itself somehow magnifying the =B3pock=B2 sound that results when the jacks pops back under the knuckle. Try weakening the repetition springs and reregulating the jack position(a little farther forward than usual) and height (so the hammer barely moves o= n a test =B3wink=B2) on one note; I believe the noise will diminish or disappear. Hope this helps.... David Andersen ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
