A metallic sound from bridge pin/string?

[piannaman at aol.com]

 Patrick,
 
This strikes me as a very real possibility.  The string seems to be working its way back up the bridge pin for whatever reason.  Negative downbearing seems like a culprit.  
 
How would I go about increasing the downbearing for one note, though?  
 
Still feeling like a novice,
 
Dave Stahl

Dave, 
With all the various suggestions about string seating and bridge pin 
tapping & gluing, I'm surprised noone has brought up the possibility 
of negative downbearing as a potential cause. 
Good luck! 
PS Is the customer complaining or is it just driving *you* over the edge?
