Thanks, Larry.  It's a grand with agraffes in that particular section.  The sound goes away with pressure on the string at the front bridge pin.

Dave... I'm not familiar with that brand and model.. If it's a grand, maybe there is a notch in the v-bar that needs to be sanded of filed smooth. I hope this helps!

 Hi all,
 
I serviced a new Bohemia 185 yesterday.  There were many voicing and tuning issues, most of which were taken care of with tuning, some lifting, sand paper, a toothbrush (my new answer to a wire brish), and a small amount of needling.
 
D#4, however, has a metallic after ring that I couldn't dispose of for any length of time.  I was able to make it go away for brief periods by seating the string at the front bridge pin (pushing down, not whacking!).  After about ten hammer blows, the sound would return.  It seems that the string wants to return to the position from whence it came, the spot of the annoying noise.  I tried to lightly tap the pin with a dowel, but to no avail.  
 
Might this be a situation where a tiny spot of CA might do the trick?
 
I'd be most grateful for any suggestions.
