What should I do if the electric guitar is broken?

Ordinary strings are not too expensive. There is no need to buy expensive strings, just buy strings that suit you. It is best to choose a sealed string (of course, it depends on whether there are holes, so buy a completely sealed string). I have bought the strings packed in paper bags. Sometimes, the strings of 1, 2, 3 are a little rusty just after they are bought back, and even the strings packed in paper boxes have encountered such problems.

As for the thickness of the strings, in fact, the instrument has been tuned relative to the specifications of a string when it leaves the factory. If you don't want to spend time tuning the piano, and there is no requirement on the thickness, you can buy the strings of the original piano thickness (les paul is generally 0. 10"-0.46 ",and mudguards are generally 0.09"-0.42". For details, please refer to the piano manual or specifications of the manufacturer official website).

Pay attention to the winding method of strings at the head of the piano. After the strings are fixed at the bridge (except for double shaking), pass the other end of the strings through the string column, then wrap them back and pull them under the inserted strings, so that the strings will lock themselves on them when they rotate.

There are also piano heads like 3 pairs 1 (such as les paul or SG series of Epiphone/Gibson), and the strings on both sides should be wound in opposite directions. In short, just wrap the thread outside. The strings should be on the inside of the piano head.

There is no fixed number of turns around the string. A piano without a string lock is easy to run if there are too few strings. Generally, 3-4 turns for bass strings and about 4 turns for treble strings are enough.

One more thing, you must hold the line when winding, but be careful not to bend the line too much. You can tighten the rope with two fingers, which will wind it more neatly.

Here are Gibson's commonly used Stopbar and two kinds of piano-horse winding methods, which should be carried out in strict accordance with the following figure:

For a new and good string, you should tune the string to the standard tone, and then pull the string: put your finger between the string and the fingerboard and dial it down. Use a little force, but not too much, one by one. Come a few times more, and then become a standard tone. When you do this job, don't accidentally break the thread, it will make you uncomfortable. ...

After several repetitions, the string is completed, and the standard is that it will not be out of tune after completion.

After the strings are fixed.

Let me talk about the tuning part first:

1. Truss bar

The principle of neck adjustment is to exert force on the neck by extending and shortening the bolt in the middle of the neck to balance the tension between the strings and the neck and maintain the shape of the neck.

1). If your adjusting screw is tied to the piano head, screwing it in the direction shown in the figure will tighten the bolt, with the neck facing back and the strings closer to the fingerboard.

2). If your adjusting bolt is located at the neck-body joint, tighten the bolt in the opposite direction.

The adjusted indicators are: hold down the sixth product 1 with Andhadhun (or hand), and hold down the last product of the sixth product with hand. It can be seen that the distance between the top of the eighth file and the bottom of the sixth file is about 0. 10 ("For inches, 0. 10 inch is about 0.25mm"), which can be measured with a feeler gauge (available from a professional hardware store).

Different neck radii (neck radius, representing the bending radian of the neck. The specific indicators of each piano can be found on their website. The required heights are different, but there is little difference. Let me list these standards and their unit conversions.

Neck radius height

7.25 inch 184 mm 0.0 12 inch 0.30 mm

9.5 inch to 12 inch 24 1 mm to 304 mm 0.0 10 inch 0.25mm.

15 inch to 17 inch 38 1 mm to 432 mm 0.008 inch 0.20 mm.

It should be noted here that the adjustment of the neck needs to be very careful, not too hard. It should come bit by bit, and sometimes you need to wait and see before you start. If you encounter difficulties, don't pull. Go to a professional to solve it.
