Good advice , John, but Al Sanderson (inventor of the accutuner) says never raise more than 20 cents sharp or else risk breaking the string. But, I guess you have been doing it without any problems. How far can one go without breaking a string? Why do you tune the bass after tuing the plain strings? "John Lillico, RPT" wrote: > Frank Cahill, > > You say, "OK, John.

If it is 50 cents flat, raise plain strings to 25 cents sharp. Rough in, THEN raise bass. All will end up real close to pitch for tuning. Increment raising is a real waste of time. The time difference between a 20 cent and a 100 cent change should be no more than 15 minutes. > > If necessary, call ahead to warn your next client that you'll be a half hour late or, skip lunch. Anything over 10 cents should be quickly corrected for stability (in about 10 minutes), then tuned rather than one prolonged pass. > > As far as a dollar a cent goes, it's much better in U.S. currency. > > John Lillico, RPT, > Oakville, Ontario, Canada -- Frank Cahill Associate Member, Piano Technicians Guild Northern Va
