Musical instruments need to be tunedregularly. If you just bought, for example, an electric guitar, you will need to adjust the scale, tremolo, string height and anchor rod. This process is quite painstaking and long. But, first of all, it is necessary to understand what an anchor is and how it is tuned.
Inside the guitar neck there is a rod,which is called an anchor. Its upper end is rigidly fixed from above under the cover at the head of the neck. And the head of the anchor from the bottom of the neck comes out, so it is available in the cavity opening. The anchor is necessary to support and strain the neck, for example, so that it does not bend under the tension of the metal strings. The need for its tightening occurs if the middle of the neck is below its ends. In the reverse situation, when the neck protrudes like a hump, the anchor must be released. Much more often, it "distributes" the deflection by waves. The setting of the anchor is necessary in the event that when playing the guitar at a moderate pace the strings are touched in frets. With a significant deflection, the tool anchor is set by the master, and with a small problem, you can figure it out yourself.
To adjust, you need an anchor hexkey. If the adjustment is made perfectly, then it allows you to get a relatively smooth, with a slight and inconspicuous curve bend. You can check it by holding the sixth string on the first and near the twentieth harmony, while you should look at the gap that appears between the seventh harmony and the string. It should not leave more than 0.2 millimeters. Anchor does not require adjustment if everything is in order.
When the rattle of the strings should be corrected their height.In the event that the problem lies in the deflection of the neck, it is necessary to adjust the anchor to adjust it. In the beginning, to avoid breaking the strings, they must be weakened. On the blind that closes the anchor nut, unscrew the bolts. Install the hexagon key as far as it will go. To reduce the deflection, tighten the anchor, for which the key must be rotated clockwise. And, conversely, to bend the anchor weaken, and rotate the adjustment tool against the clockwise direction. In the event that the anchor is loosely released, it can strongly rattle inside the neck. Normally, if it is slightly tightened in the new guitar.
It should be taken into account that the adjustment process canextremity. You can not rush when setting up a guitar anchor, turn the key slowly. In order not to spoil the neck, in a day it is necessary to do only a half turn of the key. We should wait from five to ten minutes for the bar to take its final shape, and the bend must be checked every time, making a half turn of the anchor nut. In order to avoid a nut breakdown, it is better to contact a specialist if you can not cope with the setting yourself. After the adjustment is completed, you must re-adjust all the strings, and it's best not to touch the guitar within 24 hours.
The various positions of the anchor allowexperiment with strings that have different thickness and tension, adjust the neck depending on the wear of frets and weather. When replacing the guitar with thin strings of thick strings, the setting of the anchor is mandatory. If it is adjusted correctly, then the bar from the first to the fourteenth harmony must necessarily be straight. In this case, the strings for tuning the anchor must be stretched as usual, and the neck must always have a slightly concave shape. Musicians who have mastered the tuning method described above share the results. Their instrument began to sound beautiful, the lower notes - deeper than before, high - cleaner and sharper. You can adjust the anchor on both an electric guitar and an acoustic instrument.
It happens that the root of the problem lies in defects, the slanting of the wood, the uneven twisting of the braid of the string or the uneven bending of the neck. Then it will not be solved by setting the anchor, Improving the sound of the instrument will not be even after its completion, it is necessary to seek the advice of a specialist.
