What Is Wrong With These Notes?

[Stéphane Collin]

Hi Vinny.

One possible cause for lack of sustain, especially in the range you 
described, is bad contact between string and bridge : weather string not 
resting on the bridge (then you have to tap it gently with a copper rod 
in an oblique movement against the bridge pin) or when you did this with 
too much enthousiasm, and the string is crushed into de wood of the 
bridge (then you can lift it a little with a hook).
Depending on for me mysterious causes, I found these two conditions to 
have anything between no effect at all and huge effect on sustain.
