Are you referring to the creaking sound, like rubber being tortured? That is
the problem I've found on most of the Samick products I've worked on,
haven't seen a lot of PR. I discovered the Samicks use a poor quality
version of the same "grommet" for lack of a better term, the rubber/neoprene
piece that fits in the pin on the end of the pedal rod that fits into the
hole in the end of the damper lift rod. Samicks wear out much more quickly
and are noisier until they do so. I've replaced them with Yamaha's version,
it looks exactly the same and had no more trouble! When I had none of those,
I've stolen the vitually new one from the soft pedal and put a little
Plumbers Grease on it, just a dab, that works for quite a while.
