The 25% is fine in the = plain wire sections of the piano, but it's too much for the bass. What I do = to have the bass drop right in and stay there is this:  I have the piano = stripped off anyway, so I measure the flatness in the bass on a couple notes, = looking around the bass to find kind of an average. Then I calculate 20% of = that. ( That's easy too, I just double the flatness, and move the decimal = point one place to the left. 15 cents flat becomes 30, becomes 3.0 cents)  = When I tune all the strings in the bass, leaving the strip in, then pull out = the strip and pull in the unisons, half the time I have hardly any tuning = to do on the second pass.</DIV> <DIV>    When I get into the treble, I usually go about = four notes up from the break, reset the machine, and start tuning up from = the break, unisons as I go. I DON'T reset the machine again until I get to = C5. (When I do, it always seems that I end up too sharp.)  I'll = usually reset again at C6, and C7.. Remember, I'm tuning unisons as I go. </DIV> <DIV>    When I get to about E7, I just tune the center = strings on up to the top. That helps the very top from ending up sharp. </DIV> <DIV>    This always works great for me, is very = controllable, and usually gets me right there. Then I can start my regular tuning, fidgeting, finessing, etc.</DIV> <DIV> </DIV> <DIV> </DIV> <DIV></FONT><FONT size=2>Kevin E.
