"your bass is set up well(pats self on back) but your way of o the intonation..."
yeah, i have read up on it. he gave it back to me and i noticed the way he did it. tuned the open string, and then used the harmonic at the 12th fret.
see, i was following the tune open, then fret the 12th fret. and i couldnt get it to stay in. now i know how, i wont be needing him.
though, i got the bass today, and he tweaked some of the saddle heights a bit(because when i got the bass, most of them were stripped, gotta love fender!!!) and now it plays amazing.
plus, it was 21 bucks, and took one day.
The 12th harmonic is always the octave of the open string... it doesn't mean anything about the intonation. The 12th fret harmonic compared to the 12th fret fretted is what you are looking to compare. Since they are the same note, not an octave apart as the 12th fretted and the open string are, you get rid of any errors that your tuner might have.
If the fretted note is sharp, the saddle goes back toward the bridge. If the fretted note is flat, it goes away from the bridge. You can avoid retuning byt just comparing the fretted and harmonic and make them come together until you get really close, then get them both to read "zero" and you are done.
+1 - the harmonic 12 is the same as the open string regardless of anything else, it always will be and is no indication of proper (or improper) intonation. The fretted 12 must be the same pitch as the open string.
tune, check 12th fretted, make slight adjustment, tune, check the 12th, make slight adjustments, etc.
+1. I've been doing it this way for years and it hasn't failed once. It doesn't seem as "cool", because you don't get to whip out harmonics, but it works. I wonder if techs only use the harmonic method when someone is watching......
I check the harmonic against the fretted note at both the 12th and 19th fret. If I can't get them both perfect, I split the difference. This is the best method I have ever used. I found it in a Bass Player column written by Rick Turner years ago.
