Re: Intonating a Music Man Floyd?
you actually have to compare the 12th fret harmonic to the 12 fret fretted note.
If the fretted note is flat, move the bridge saddle closer to the neck. If it’s sharp, move the saddle further from the neck. You want the fretted note to be the same as the harmonic.
but each time you move the saddle, make sure to tune up with a tuner. Intonation position of the saddle is specifically relative to the string gauge/tension and tuning. So when your tuning changes after adjusting the saddle, you need to retune, check the harmonic vs. fretted notes, and adjust again, repeating until they match.
The nice thing about floyds is that their setup in terms of string/spring tension is also specific to string gauge and tuning, so if you set up everything once, any time you change strings, as long as you're using the same brand/gauges/tuning, you most likely won't need to change anything in the setup.
If you are changing brands/gauges/tuning though, be prepared for pain in your ass.
