Hi Ron,

Over a time period of 3 months. Unisons were cleaner to my ear on the
"treated" pairs. 

I do think that machine "zeroed" unisons may have an unsatisfactory sound.
I really should repeat this process with another instrument and try to take
careful measurements. There is the problem of coupling to deal with when
taking individual measurements at this level--i.e. the "Virgil" effect. I
suppose one could go farther and try this experiment with *only* coil
tapping, and another instrument with only string seating/bridge pin taps.
