>... Do you know if the 5 minute tuning/pitch correction was close enough to >pass the PTG test? Or was it checked in that manner? >Don Rose First question: no, I don't. Second: Don't know the criteria for checking either. Never thought to ask such a thing. He indicated he practiced for sometime lowering 100 cents, raising 100 cents on the same Acrosonic before doing the Guinness thing. Just the ability to do such an act is quite astonishing. That's manipulating each tuning pin at an average of 3.41 seconds per pin. My understanding is that it was a passable sounding tuning. But PTG 80% minimum standards ... doesn't seem likely possible from where I sit, but you'll have to ask the man himself. He a straight ahead individual, all the way.
