I have had a couple of technicians observe the wire is not perfectly straigh=
t=20
in the last inch of travel into the agraffe, and measurements seem to confir=
m=20
this. The theory is this acts like a shock absorber, or a mild kink, and=20
affects the string adversely. In fact strings are kinked daily by technician=
s and=20
they don't re-straighten. I had thought Baldwin did this for tone quality's=20
sake, but it's obvious to me on reflection that indeed it's just for handlin=
g=20
ease. I'm guessing Mapes used an industry standard straightener, and i'm sti=
ll=20
wondering if roller pressure on the skin of the wire affects it for ill ?
