tuning question

[Robin Blankenship]

Three half steps probably qualifies you as a primo candidate for my
"HeldenTuner Award". I have often seen the same affect of a huge pitch
raise. My conclusion was that such a large change in the total tension on
the back causes it to flex a bit. As the tuning pin position corresponds to
the string location (left-middle-right = low-middle-high) that the top of
the pinblock ends up skewed relative to the bottom of the pinblock. Hence,
different "results" from the same process.
