Today is the analysis of the product and the neck. The original Fanta was thin and low, and the players usually just plucked the strings or played jazz. In the early days, I used to use the thick string high stroke method, and rarely pushed the string. Gibson introduced a wider but lower product, which brought more sustain. Of course, this is also related to the heavier piano body. There is a fact that wide products will bring the problem of inaccurate intonation. Because it enlarges the contact point between strings and frets. In the late 1960s, higher quality products became popular. On the one hand, players want to improve their speed through small moves, on the other hand, they want to find a fulcrum to push under the strings. It is becoming more and more common to replace fenders with higher ones to make up for the round fingerboards of early fenders (see figure 1). When the piano position is pushed to the top of the middle arc, the circular fingerboard will "suffocate" or cut off the sound of the treble E and B strings. Although this can be avoided by adding action, using higher quality can make the strings pass through the arc top without adding too much action. Today's fingerboard is getting flatter and flatter. (Figure 1) Tall and thin product, which is convenient for pushing strings. Bring smaller movements and better pitch. But your style should determine the type of products you use. If there are a lot of sliding strings in your style, you will find that playing high-quality music is like bumping between rails. Or, if your fingers are thick, you will find that there is not enough room for your fingers at 12 or above. Try different products and find the type that suits you. Tip: high-quality products need strings. If the strength of each finger is different, the chord will be out of tune. The distance between Gao Pin and his fingers is also very high, so there is more room to go out of tune. This is a good place to discuss scallop necks. The neck fan refers to carving grooves between the frets on the fingerboard, so that very high frets can be made. Theoretically, this enhances the expressive ability of timbre: for example, it enhances the vibration, makes the string pushing easier and improves the speed. In fact, this will make the pitch difficult to control. Guitar masters (Larry Carlton, Yngwie Malmsteen, John McClellan, etc. People who play scales spend a lot of time mastering pitch. If you must try this scale neck, you'd better consider trying another guitar. In this way, your guitar can be used for ordinary playing. No matter what kind of products you choose, it is important that they be smooth and flat-that is, they should be well polished and at the same height. Worn points may make the voice tremble or inaccurate. New products can be adjusted by polishing. This procedure includes polishing the high quality product to the same height as the lowest quality product, and then fine polishing it. The most important thing is to get the correct pitch when the string touches the fret and then polish it. You'd better adjust the tension in your neck after polishing. You will find that the guitar becomes better and sounds better after polishing. Good fret polishing can even make up for small deformation or distortion. If your guitar is very old, the frets have been polished so many times that there are almost no frets, or the neck is badly twisted, or you need a new product. At this time, you can do some work on your products, or replace all new products. This is a high-tech and very complicated job, because its complexity is also quite high. Before you pay, you should consider whether I like this neck or not. Do I like the feeling of it in my hands? Or, if it is to adjust the neck distortion, is the neck stable after work? Is the deformation fast? If you have any doubts, you can consider buying a new neck (assuming your neck is detachable). Replacing the whole neck is more reliable than replacing silk, and it will only cost a little more. If you are satisfied with the present fingerboard, let's do the fretting work. First, get rid of old troubles. A good pianist will check whether the fingerboard is straight or not. At this point, the fingerboard arched or deformed by heat should be restored to its original state, provided that the fingerboard is thick enough to be restored to its original state. Another process before fretting is to smooth the circular fingerboard. Warning: cheap fretting work is cheap because they don't repair the fingerboard. An untrimmed fingerboard means that you need to finish it in a short time. Silk works. A good quality guitar plays much better than a poor one. Note: Sometimes, people consider changing the quality of silk just because it is badly worn. If only the harmony rhythm of the chord position is played, only the first three products will be pitted, and the other products will be the same as the new ones, then it may really be necessary to change the silk. Besides, you just need to polish it. The neck of a guitar with a neck is usually made of one or more of the following kinds of wood: maple (maple), rosewood (rosewood) and Mathogany (ebony). The wood around the neck affects the sound. For the neck, the first thing to consider is "stability". When the wood is still "green" or just cut down, it will be made into a neck without storage, and the consequences can be imagined. In the "good old days", wooden musical instruments, including early electric guitars, were made of wood stored for many years. After the wood is made into the neck, most of the storage processes are completed. This is one reason why old guitars are valuable (other reasons are collection value), and they are stored for a long time. If an old neck could be deformed, it would have been deformed long ago. If the neck of a Fender guitar in the 1950s stays straight, it will certainly do so in the future. Now, no one has time to let wood be stored naturally. Many kinds of wood are dried in a specific room, or manual procedures are used to improve the stability of wood. Maple is the most commonly used wood. If the neck of the piano is not full maple or maple with independent maple fingerboard, it is a good choice to add rosewood or ebony fingerboard to the neck of the piano. The timbre of maple fingerboard is brighter than rosewood. But it is easy to be worn and faded. Note the maple neck with dark flame pattern. They are really beautiful, but they are more unstable than ordinary maples. Rosewood is the most used wood in fingerboard. The whole rosewood neck is beautiful but expensive and heavy, which has little effect on the timbre. The whole rosewood neck and the neck with rosewood as the fingerboard sound more melancholy than the whole maple neck. The weather is warm. Not easy to wear and fade. Ebony is rarely used for the whole neck. It is very expensive and heavy, because it is the most valuable of the three main kinds of wood. However, ebony is usually used for fingerboards. Provides the same brightness as maple, and is not easy to wear and fade. Ebony fingerboards are often matched with mahogany necks to reduce the brightness of some sounds. (Figure 2) Exotic wood, such as African Gwen and Indian laurel, can be used as the neck. However, although these Woods are beautiful, their timbre and stability are nothing special. This is why ordinary wood is good. They can stand the test. Even the most stable neck sometimes deforms in extreme circumstances. Most necks have a metal bar through them. By adjusting this pole, you or the pianist can straighten the deformed neck. The neck of a guitar is usually arched (bent inward) or bent backward (see Figure 3). Many experts spend hours observing whether the neck of a guitar is straight from the end to the head. That's good. If you want to buy a new guitar, whether you keep some parts of your guitar or get an assembled new guitar, the following steps are necessary. Adjust the bridge horse to adjust the height of the string first, so that it can be more comfortable when bouncing off the string. Now play the middle part of the neck (frets 5 to 9). If the chord of this section is high, the neck may bend inward. If this is the case, tighten the metal rod in the neck. If the strings are vibrating (referring to the sound heard from the speaker after being plugged in), they may protrude outward. At this time, the metal rod needs to be relaxed. If this doesn't work, you should find a pianist to help you adjust it. Next time, it is the analysis of the piano body and plucked strings.
