I find that the bass needs about 20% overpull. When the machine finishes it's = calculation it comes on at AO, right? I go up an octave to A1, look at = the cents deviation, and measure how flat it is. Then I go to A2, which on = most pianos is still on the bass bridge, and I measure how flat that note = is. Then I do a quick calculation in my head to get the average cent value. = Twenty percent is an easy figure to calculate. Say it's 32 cents flat; double = that for a value of 64. Move the decimal point over one place and you have = 6.4, which is twenty percent of 32. I adjust the machine to be 6.4 cents = sharp, tune all the single strings and the non-muted bi-chords, pull out the = strip and tune the unisons, and the bass will be dead on after the rest of = the pitch raise process. (Of course, I always go through it a second time on the = final pass, sheesh, I'm not a hack, after all.) </FONT></DIV> <DIV><FONT face=Arial size=2>    Think about it, = you might try it.
