It doesn't take any time to push down the bass keys with much of your upper body weight. That's the first test before you even think about pulling the action. If the knock goes away, check for a loose cheek screw. If the knock remains then your free minute is up. ---Tom Gorley On Dec 12, 2010, at 8:09 PM, Paul Mulik wrote: > Hello list, > > A couple of days ago I did a couple of tunings for a church, and just as I was about to leave they asked me to have a quick look at a third piano, a Kawai KG-2S grand.

Is this likely to be due to a gap between the key frame and the keybed, or should I look for something else? I'm going back on Monday to have a better look. > > Thanks, > Paul Mulik, Joplin MO -------------- next part -------------- An HTML attachment was scrubbed...
