Choice and purchase of guitar:
How to Choose a High Quality Guitar
1. Accuracy is the core issue. After tuning the strings according to the guitar’s timbre standard, the overtone of the twelfth part of the string is produced. If it has the same pitch as the twelfth part of the string, it is qualified. So check the six strings in turn.
2. Next, check the feel. Poor hand feel will force you to adopt improper chord method, which greatly hinders the improvement of left-handed technology. When the guitar is tuned to a standard pitch, the distance between the string and the fingerboard should be about 4mm at the 14th character. Too high, the strings will feel laborious, and vice versa will cause the phenomenon of goods. Good hand sensing should be in the absence of typing and any noise, the left finger can easily press any sound, big horizontal press also does not feel laborious.
3. Check the sound quality. When playing the fifth overtone of each string, the guitar with poor resonance often fails to produce a bright overtone. And then do all kinds of strings on the piano, the volume should be changed dramatically. At the same time, the guitar strings with good performance are balanced in volume, sensitive in pronunciation, bright and pure in treble, deep and thick in bass, and the volume of high position will not decrease.
4. Examination of other parts. See if the gear of the chord shaft is damaged, whether the rotation is smooth, whether the panel, back panel is cracked, whether the paint is bright, whether the piano color is coordinated. The most important thing is that the silk must be smooth and the fingerboard edge can not be rowed.
