<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Old hammers were lighter than the new ones, but new ones (Renner
Wurzen AA) are in the middle of the Stanwood strike weight standard. I have
rebalanced the keys and the front weight is just under the maximum advised, so
I didn’t modify the geometry. Bass improved much, probably thanks to the
extra weight of the hammers. The treble, though, sound dead with a knock on
wood noise far from musical.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So I wanted to see if my bag of tricks for getting the treble
hammers right is up to date. One must know that I exclude the acoustic body as
culprit, because, as I said, the old treble hammers did sound very well.<o:p></o:p></span></p>

with list wisdom if there was something more to try before that.<o:p></o:p></span></p>
