How do you fix intonation on an acoustic guitar?

How do you fix intonation on an acoustic guitar?

Intonation is adjusted by increasing or decreasing the length of a guitar string. The easiest way to do this is by adjusting the position of the guitar’s bridge. On some guitars, adjusting the bridge position is an easy job. On other guitars such as acoustic guitars, this is almost impossible.

Do acoustic guitars have intonation?

Most acoustic players take their guitars to a qualified guitar technician when they need their intonation adjusted. Typically, proper acoustic guitar intonation begins with a full setup, along with a fresh set of strings.

Does changing string gauge affect intonation?

String gauge does affect intonation, but just a little bit. Having a perfectly intonated instrument is almost impossible to achieve. There are too many factors accounting for the intonation change. Action height, bridge saddle position, neck radius, nut position and height, and so on.

What causes bad intonation?

A worn down or improperly positioned nut can cause bad intonation. A worn-down nut will need replacement, and a nut set too high should be filed down in order to lower the string action.

What guitar has the best intonation?

A longer-scale guitar will tend to have better intonation than a shorter-scale guitar. And a lower-action guitar will have better intonation than a higher-action guitar. Finally, the fret height can have an effect. So get the guitar with the longest scale, lowest action, and smallest frets.

How do you check Acoustic intonation?

To check your guitar’s intonation you will need a tuner preferably, a chromatic tuner. Tune your instrument to pitch and fret each string naturally at the 12th fret. This note is one octave higher than the open string note and should be in tune (neither flat nor sharp.)

Can new strings affect intonation?

When changing strings, the type, make, and gauge of the strings may affect the intonation. When changing to a new type of string you might expect the quality to change. New strings will be different than old used strings of the same make. Take Away: Heavier Strings means more error.

What causes guitar intonation problems?

If the tops of your frets are too flat, dented, or you just had crappy fretwork done by a bad guitar tech, you can have trouble setting intonation. If this is the case, you’ll probably have other issues too, such as fret buzz or notes fretting out. Overly flat frets can cause intonation issues.

What kind of saddle does an acoustic guitar have?

An acoustic guitar generally has a fixed saddle (of bone or whatever). The fact that the saddle is installed at a slight angle (increasing string length from 1st to 6th) string is a nod towards some string compensation. The pre-shaped, compensated saddles that many guitars have these days is another step in the right direction.

How does intonation work on an electric guitar?

On most electric guitars and basses, intonation is adjustable at the bridge. To set intonation, you’ll need to find the screw that allows you to change the position of the saddle and therefore the length of the string. On a Strat or a guitar equipped with a tune-o-matic bridge, each of the six saddles has a screw that sets its position.

Where does the nut and saddle go on a guitar?

From there, they’ll usually address the nut and saddle, where the strings stretch over a piece of bone, plastic or other synthetic material. Most saddles are placed at a slight angle to the bridge, which adds length to the lower strings to adjust for differences in string thickness.

How is intonation compensated on a steel string?

Most steel string designers provide for intonation compensation by striking a compromise between each of the individual ideal saddle positions, placing the saddle at an appropriate angle:
