Please! I've a customer with a newer Kawaii grand with wood whippens and black plastic jacks. She has noticed (I confess I can barely, and never would have heard it) a slight rubbing sort of sound when a couple of keys are played very softly and slowly. Looks/sounds to me like sound occurs when jack is activated. I notice that jack spring on her piano goes into a hole in the jack which appears to be a looser fit than my older Kawaii with wooden jacks, I've tried a tiny drop of clp lube in spring hole on jack and on jack centerpin with no result. I'm pretty sure sound is coming from jack area, Anyone have a similar experience?! What do I do?  Thanks in advance for all advice!!   Jon</font></font></blockquote> </body> </html>
