Intonation
Intonation is when we adjust the saddle position so that every note on the fret board plays in tune.
To adjust the saddle position we turn this screw
here
As we can see, this screw here
Moves the Pivot Point
And the two stops
And the string holds the top of the saddle in the same place.
So the saddle's position in Zone 2 changes when we intonate. Watch it again.
So we have an extra step
We must re-position the saddle in the playing position using the tuning peg after adjusting the intonation screw. Watch
These two steps in action. Notice, we start in the recommended playing position, with the bottom of the saddle, very near the front stop for fast bending. This playing position is covered in Scene 5 'Easy Bending'.
To make the string length shorter we move the pivot point forward by loosening the intonation screw.
Then we tighten the tuning peg until the saddle is back in the perfect playing position.
Tightening the tuning peg to reset the saddles playing position is necessary because when we move the pivot point forward the saddle falls back away from the front stop.
Now to make the string length longer, first loosen the tuning peg.
then tighten the intonation screw.
Then check saddle position and re-adjust to the perfect playing position with the tuning peg.
Now we want to go over what intonating is and why it is great to do.
For people already confident with intonation, this video is over.
Most guitars are tricky to intonate and so most people never do.
A well intonated guitar is a very beautiful sounding instrument and since the EverTune bridge is so easy to intonate, we highly recommend it!
Intonating is adjusting the length of the string so that the notes high up on the fret board,
frets 12 and higher, are as in tune
as the notes low on the fret board.
To intonate a string, we first tune that strings open note. The open note is the note played when we pluck the string without fretting it.
Once this open note is in tune, we then check the tune of the octave. The octave note is the note we hear when we pluck the string while holding down the string at the 12th fret.
If the open note is in tune and the octave is sharp, then we want to lengthen the string. We lengthen the string by turning the intonation screw clockwise.
Here is a full example of intonating a string in this way.
First pluck the open note.
It's in tune. Now fret the 12th fret and pluck.
It's sharp. So we first loosen the tuning peg.
Then we turn the intonation screw clockwise.
Then we reset the saddle position to the playing position.
We have now successfully lengthened the string. Now we check our intonation again to see if we have lengthened it the right amount.
Still a little sharp on the 12th fret. So we will lengthen the string again.
This string is ready!
One last example. First we pluck the open note.
Then the 12th fret
The 12th fret note is a bit flat. So now we want to shorten the string which means we loosen the intonation screw.
And reset the saddle position with the tuning pegs.
We have successfully shortened the string. Now we re-check intonation to see if our adjustment is sufficient.
still a tiny bit flat.
Perfect.
