Hi Lance

Interesting report.  I would not have imagined that smoothing the kinks 
would have much of an effect. But then it sounds like you did really 
more then just smooth them out.... you  stretched the whole area 
adjacent to the kinks with a string hook... which is interesting also.  
I will definitely give kinks a closer look in the future.

The below is something I've posted about several times with regard to 
the idea that loose pins are a direct cause of false beats. This similar 
reduction between screwdriver and vicegrips speaks of a more general 
condition of springyness at the termination. As does a few other facts.

Cheers

    I also noticed a muting of the false beats with a screwdriver
    pressed on the
    offending string at the bridge cap AND I noted a similar reduction
    with a
    pair of visegrips put on the back bridge pin.  Thanks again.
