<HTML><HEAD></HEAD> <BODY> There are some excellent articles by Bill Spurlock in the Journal and on the Journal CD, I believe.  Use something to block the bass strings from sustaining and play the offending note.  If the ringing is gone the bass dampers are the problem, which is typical.  Often they are 1" dampers.  That Yamaha has 2 & 3/8" dampers, I think.  Replacing the bass dampers and regulating will take care of the problem.  If after blocking the strings the offending note still has some ringing, then move that tenor damper up and down and make sure it is seating correctly.  Change it to a bi/tri-chord.  The over-damper is usually the last resort and most often you can fix it before that. Good luck and be sure to read the Spurlock articles under "Basic Skills" or something like that...
