The influence of the neck and its components on the sound

To make a beautiful guitar, the panel is the most important, and the impact of the headstock on the guitar sound is equally important. Today we will take a look at how the neck and its related components affect the sound of the guitar.

Neck: In order to facilitate the transmission of sound, the neck material needs to be tough.When the strings are moved, the kinetic energy begins to pass.If the material used for the neck is soft, the kinetic energy will be transmitted in all directions and will not be transmitted in the direction of the bridge, so the selection and design of this part is essential.Mahogany is the most common neck material, but the Spanish toon has also been in the limelight in recent years.This wood tone is very similar to mahogany. Maple is also the wood of the commonly used neck. The core wood is hard and light, and it is easy to obtain a solid structure and a sleek form. The neck used to make the guitar is very effective in preventing guitar distortion.At the same time, the mahogany wood grain is beautiful and charming, which is very suitable for beautiful head carving decoration.

Heel: This part is the same as the headstock of the guitar. Some special high-end models or retro models are made of the same material as the neck. In most cases this part is a few pieces of structure. Different acoustic guitars have different shapes and sizes. It is also the position of the second strap button.

Neck Joint: Wedge embedding or glue bonding – is the traditional method of connecting the neck to the body. This is the “tail” of the neck, which is also a continuation of character, usually cut to better match the body. This part is the key to the fit. If the cutting is slightly unreasonable, the joint between the neck and the body will be poor, resulting in air mixing and affecting the sound when the body is bonded.


The upper nut must be hard enough to withstand the wear caused by the string vibration; However, it also needs to have a certain degree of flexibility, and it is impossible to bind the position of the string.String and hoses need to be polished very neatly. The upper and lower nuts function a bit like the gatekeeper of the pronunciation panel, which blocks part of the vibration and allows effective vibration to pass. Its unique characteristics also have an impact on sound. Again, some frequencies will be suppressed and some will be enhanced. This impedance matching between the strings and the pronunciation soundboard affects the efficiency of the nut and helps create perfect tones and continuous blending. The upper nut can be made from a variety of materials: synthetic ivory, plastic, bone, and the like. The material also affects the sound, such as the difference between the sound of the bone and the brass.


Most acoustic guitar fingerboards are ebony or rosewood, and of course there are some artificial materials, such as Richlite. Ebony is a must-have fingerboard material for advanced guitars. It is naturally black and black, the wood is very hard, and the wood is rich in oil and fat, which can ensure a good hand. The more upscale guitars, without exception, use African ebony fingerboards. It is used as the main reason for the fingerboard material in addition to the tone, but also because the material is hard and not easily deformed. This kind of wood is extremely hard and can be used on the guitar fingerboard to increase the tensile strength of the neck, making it less prone to deformation. Rosewood fingerboard is generally used for low-end and mid-range guitars. Its wood is hard and can effectively ensure that the fingerboard is not deformed, and its durability and vibration transmission are good, so it is one of the commonly used wood species. It is very comfortable when used on the fingerboard, and it is elastic and can reflect the playing intensity sensitively.

Frets: Most of the silk material is usually made of Nickel silver, which usually appears as an NS alloy (actually free of any silver). Its actual composition is an alloy of nickel and copper. In recent years, some silk manufacturers have begun to introduce Jescar’s harder, more wear-resistant stainless steel (SS) yarn. Compared to electric guitars, acoustic guitars are more slender, because there are not so many strings in the performance. In general, the influence of different silks on the sound is much less than the impact on the hand.

Truss rod:

It is used to adjust the curvature of the neck from the head to the sound hole.

The main material is steel, and now there are many composite carbon fiber ribs.

When the guitar is in use, it is affected by the environment, temperature, humidity, etc., and the neck will always have a slight change, which will lead to problems such as hitting the product and the pitch is too high. The ribs are present for easy adjustment of the angle of the neck. The adjustment principle is very simple: tight inner band – the neck is tilted back; The ribs – the neck is bent toward the soundboard.
