Here's a little secret about the wooden guitar: the luthier doesn't really care how much water is in the wood. Indeed, most of the luthiers don't care very much. Although the weight, density and other indicators will change with the change of wood moisture content and will affect the resonance. But this is not the main problem. We should acknowledge the fact that wood will change its size and shape according to the amount of water content in the environment.

The growth of trees is a process of dealing with water. About half the weight of a tree is water. When a tree is cut down, the water begins to evaporate. This process is called "air drying". At this time, the wood volume will gradually shrink. But the direction of contraction is uncertain. Uneven shrinkage is an important challenge for woodworking.

 After the wood is dried, it will absorb water when the water content in the environment becomes higher, and it will lose water when the water content in the environment becomes lower. The result is that the length of the wood does not change much, but the width and thickness expand or shrink.

With this understanding, we can discuss the deformation of the guitar panel and back panel. The panel expands and shrinks with the change of humidity in width and thickness, but the sound beam on the panel inside the guitar does not. As long as these immovable sound beams are glued on the panel and back panel, contradictions will arise. On the one hand, the width of the panel and backplane will expand and shrink with the change of humidity in the environment, on the other hand, the sound beam is preventing this process. If the humidity changes dramatically, the wood will deform (high humidity) and crack (low humidity) when releasing stress.

This is one of the reasons why the luthier arches the panel and back. Guitars are usually made in a "loose" condition to prevent the wood from shrinking. In addition, the luthier will assemble the guitar in a suitable environment (humidity: 40%~50%, temperature: 21 °). Minimize the impact of humidity on the guitar.

The wood guitar produces good sound quality but require proper care to keep them safe from bumps and drastic weather changes. It also needs regular tuning and maintenance to last you a long time. Among countless materials available, carbon fiber has the characteristics of being lightweight, has good strength, and boasts extreme durability. When these attributes are applied to a guitar, everything becomes a perfect combination.

Joytar hope to create a compact, versatile, and powerful guitar to accompany you every step of the way.
