<DIV>>The problem is that there is not enough weight on the damper =
lever to
pull <BR>>the damper down on the string. If you take out one of the =
levers,
see if <BR>>there is room to add another lead weight. Chances are =
there is
not, so there <BR>>is really nothing that can be done to solve this =
problem. It is an <BR>>engineering problem. But don't expect the =
company to
help you. One possible <BR>>solution, (one that I heard about on =
the list),
is to add a fishing weight <BR>>(the kind you clamp to a fishing =
wire to
help the lure sink), to the damper <BR>>wire. This will give the =
damper
lever/wire enough weight to help the felts do <BR>>their job.

<DIV><FONT color=#000080>If the problem is a lack of adequate mass, =
extra
spring pressure will not improve damping but will increase touch =
weight.
It takes both mass and spring pressure to do the =
job. (See my
Journal article on the subject.) </FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#000080>Another way to add weight without pulling =
the damper
tray is to add it to the damper head itself. You can drill from =
the bass
side using a Forstner bit or a spur bit and install one or two damper =
lever
leads as necessary. Black over them with a felt pen and they =
will be
barely visible.</FONT></DIV>
