have a situation where the "knock" is very noticeable that the key frame
is knocking against the key bed. I see no adjustments anywhere to
correct the problem. As a temporary solution in the treble, I
folded several business cards in the gap to quiet the "knock". I
suspect this was not originally a product for the US but brought in by
someone that purchased it while overseas and brought it back with
them.<br><br>The cheek blocks have a metal plate that allows for front
to back adjustment, but no adjustment for "up/down"
adjustment.<br><br>Anyone experienced this before and what was the
resolution?<br><br>Thanks in
advance,<br><br>-------------------------------------------<br>Ken
