harmonics and saddles

[gorgeousgeorge]

Sorry to disturb you all again but I'm tearing my hair out and getting exasperated after raising the saddles I now find the harmonics are out above the 12th fret as the increased height obviously stretches the string further .The harmonics were correct before raising the saddles.It's no problem to do it again(though a p.i.t.a.) but I ask is it normal practice to re-do the harmonics after saddle adjustment when they were previously ok.
thanks for any opinions

Hi George,
It is very normal to have to adjust the intonation again after changing the saddle height. This is because the string tension increases with a higher saddle, or decreases with a lower saddle.
