  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.  I literally had one minute to look at it, as the choir was entering the room to practice.  I didn't have time to pull the action.

  Anyway, the lowest 5 or 6 bass notes had, in addition to their normal sound, a knock, like wood knocking against wood.  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
