Adjustment of the action of the guitar

 

 

The action of the guitar is the position of the strings in opposite of the fingerboard.

For this reason the action of the guitar will influence the force that have to be used on the strings but also the tone of the guitar.

The action of the guitar must be adjusted in a way that the force you have to put on the strings is not too high.

If the action is too high the playability will decrease. Is the action too low the strings will rattle against the frets.

So its necessary to find the correct balance in adjusting the action.

The advantage of a higher action is, more volume, better sound, easiness of taking chords.

Disadvantage of a higher action is, too much pressure to make a tone, fast runs are more difficult to play.

The advantage of a lower action is, less pressure is needed to make a tone, fast runs are easier to play.

The disadvantage of a low action is, rattling strings,  less volume, lesser quality of sound.

To adjust the action you must experiment with the height of the bridge and the comb.

To lower the bridge you can deepen the groove with a file or saw. To raise the bridge you can put a piece of wood beneath the bridge. In this case a new bridge will be preferable.

The comb can be treated in the same manner as the bridge.

Once the action is adjusted in a correct way (which can take some time) it will last for a long time.
