body structure
Here the main description of the electric guitar body joint. The body of the electric guitar is made of one or more pieces of wood, which are bonded by special glue. The glue used to make special glue for the instrument is also used in all other structural parts of the electric guitar that need to be glued together. The glue commonly used in the traditional process is leather glue, which is a sticky substance made by boiling the skin of an animal. From the point of view of musical instrument manufacturing, the advantage of leather glue is that it has high bonding strength, is not easy to penetrate into wood, does not affect the acoustic performance of wood, and because the leather glue will return to a fluid state after heating, when the musical instrument is damaged, the bonded parts can be separated simply by hot air heating, thus replacing or repairing the musical instrument. However, because the leather glue needs to be boiled before gluing and comes from animals, the bonding of modern mass-produced electric guitars basically adopts industrial synthetic glue dedicated to musical instruments. Generally speaking, since the spliced piano body cannot guarantee the consistent acoustic characteristics of each wood part, and the splicing place will cause vibration loss, under the premise of the same wood variety level, the smaller the number of spliced wood, the more stable the timbre and sustain of the electric guitar. Common electric guitars are basically spliced by two pieces of wood, one large and one small, and large pieces of wood will be perforated and slotted for installing the neck and bridge. Cheaper electric guitars will use more pieces of wood, while electric guitars made of a whole piece of wood are very rare and are basically customized.
The electric guitar body structure also involves hollowing and opening problems. The electric guitar body has different structures such as solid, semi-hollow and hollow. The solid electric guitar was first invented by Gibson and is also very common. The body of this kind of guitar is solid wood. There are different degrees and different ways of hollowing out inside the body of the semi-hollow (Semi-hollow) electric guitar. The main purpose of this semi-hollow structure is to reduce the weight of the guitar, improve the guitarist's playing experience and reduce the burden by reducing wood. With the development of technology, some semi-hollow structures also provide additional acoustic functions, such as lengthened sustain tones, etc. [11], but in any case, the hollow part of the electric guitar body of the semi-hollow structure will not be exposed, nor will it directly affect the sound; hollow The electric guitar is similar in shape to the electric guitar, and it is also equipped with pickups, but it has a complete resonance box and sound holes for sound.
