<DIV><FONT face=Arial size=2>Hi all Wurzen punching =
lovers.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I still believe it is the quality of =
shock
impulse transmitted to the case that comes back into the string and =
mixes with
the string energy to produce this or that sound in the =
end.</FONT></DIV>
<DIV><FONT face=Arial size=2>I still believe that too hard =
punchings give a
disturbing tac tac noise when playing loud in the =
trebble.</FONT></DIV>
<DIV><FONT face=Arial size=2>I still believe that André's =
punchings are really
great (the exact firmness for sound vs regulation) : no tac tac, no =
where is
the dip, and good thump quality.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My unauthorized thought.</FONT></DIV>
