<DIV><FONT size=3> I think 2 things occur here. Yes as yo=
u say
it is the soundboard If it's got enough crown could push tenor strings
sharp but I may be a tension differential in the plate & what =
you
wrote about the dramatic cents change makes me nervous. </FONT></DIV>
<DIV><FONT size=3> Ie done this many time when re-stringing a =
bass
section but not as you describe. A bass section has far more inherent tensio=
n in
it but less effect from the board. I wonder about the plate distorting. I'm
thinking out loud but as the treble strings come off the board does come up =
but
also the tension being released might allow the entire tenor go sharp as
plate decompresses & pulls the other strings sharp so to
speak.</FONT></DIV>

<DIV dir=ltr>Just out of curiosity when I got the treble strings off, I
measured the pitch of C5. It was 76-cents sharp. After I insta=
lled
the new strings and put enough tension on each unison so it didn't sound f=
unky
and enough to keep the coils tight I measured again and C5 was down to jus=
t
16-cents sharp. I then chipped twice and measured again and C5 =
was
down to just 4-cents sharp. By the time I started to actually "tune"=
it,
C5 was just barely off.</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Since the sounding board could raise the pitch that much, i=
s this
a good indication that it has not suffered terminal compression set? =
It
would seem to me that the board would still have to have some life in it t=
o do
that.</DIV>
