Bare Bridge

[Jim Coleman, Sr.]

HI Del:

I have not noticed any difference in friction as to whether the bridge 
surface is coated or not. The down bearing upon the bridge is small 
potatoes compared to the two angles the string has in going around the
bridge pins. The friction at the bridge pins would be somewhat similar 
to the friction going through agraffes or under Capo Bars. You will 
notice that we do not lubricate the bridge pins or the Agraffes.
