intoneation

[thunderider]

ive just lowered the bridge on my tbird, and was wondering the easiest/quickest way of checking this?or just doing that wont affect it?

I take it you mean check the intonation? If that's the case then it should be fairly easy. Plug your bass into a tuner and tune it to pitch. Then play the harmonic over the 12th fret, pluck the string while touching it but not fretting it. Watch the tuner to see how the tuning compaired to the freted note. If they are different then you need to adjust the intonation by moving the saddle back and forth until both are in tune.

kewl thanks

Why check the harmonic over the 12th fret rather than the actual fretted note? Or are you saying check both? Or something else.

He's saying compare the two, the fretted 12th fret note and the 12th fret harmonic should be the same pitch. If they are not, then the intonation is out.

Some do this at the 17th fret too - usually the people that regularly frequent the dusty end of the fretboard

[BassBus]

As you press the string down onto the fret that action stretches the string a little. That will change the intonation itself. So if you can get the intonation of the harmonic as close as possible to the fretted note at the twelfth fret then the open string notes will be as in tune as the fretted notes at the other end of the neck. Never heard it being done at 17th before but why not.

Simple way to remember how to do it using a tuner - 12th fret harmonic v 12th fretted note , use the '3 f's' rule , if the [b]F[/b]retted note is [b]F[/b]lat move the bridge saddle [b]F[/b]orward

Unless you have [url=http://www.truetemperament.com/site/index.php?go=0&sgo=0]true temperament[/url] frets, only the 12th fret harmonic should be in tune with the fretted note.
