SAT FAC help please...

[Dick Beaton]

Lance...
Remember that FAC doesn't work well if the F3 is a wound string.  You can
get the number from the first plain wire string and use that for your F
reading.  Jim Copleman Sr. sent out some  info on this problem. He used one
page number for the notes in the bass and another for the rest. The other
option is to use the old F4 method which gives you tuning info from C3 to
F6...than tune the top and bottom by octaves, or any other way you like.
Baldwin sold more Acrosonics than any other piano, but it could have been
scaled better.
Best wishes,
Dick RPT MT
