String Breakage of the Third Kind

[Keith Roberts]

It strikes me as funny an eight year old string would break there unless the
wire was corroding at that point. If any more break, I would think about a
reaction between the dissimilar metals of the bridge pin and wire. Obviously
the speaking length pin takes the most stress of the two pins so the wire
should break there first. If there is not enough downbearing, maybe the
string is cutting itself in half because it's riding up and down on the pin.
Just shooting in the dark.
