<dd>In all my years of doing this, I've never run into a piano where the
monochords needed that much of an overpull! I, too, would be afraid to do
that! IMO, it isn't necessary. <br><br>
<dd>I don't even use the PR function on the SAT for the bass strings. I
start with #1 and just pull them a little sharp and go! They usually come
out pretty close. <br><br>

<dd>I've been chicken to try that big an overpull percent on the
monochords, for fear of breaking them.<br><br>
<dd>In the TuneLab Pro documentation, Robert Scott recommends 12% for the
bass bridge and 30% elsewhere, for small to moderate pitch raises.
For better results (tuning unisons as you go, bass to treble):<br><br>
<dd> bass
bridge
12%<br>
<dd> tenor bridge to G5
29%<br>
<dd> G5 to
G6
29% increasing to 37%<br>
<dd> G6 to
C8
37% decreasing to 14% (tension gets high up there)<br><br>
<dd>TuneLab's ability to measure each string and calculate a precise,
individual overpull percentage in realtime is one of its best features, I
think.<br><br>

<dd>I use a VT also Andrew, and I find that the upper end of your percent
ranges work for me in the tenor and treble. However, I find that the
bicord bass needs closer to 25% and for whatever reason - I certainly
don't understand it - the monocord bass needs about 40%. I know, I've
never heard of anyone using that much overpull in the low bass, but for
whatever reason, if I don't, it'll come out flat. Strange.<br><br>
