There are several primary types of wood that a ukulele can be made from, and variations often exist for each one. Buyers should keep in mind that the quality of the materials and the craftsmanship of the instrument affect a ukulele's tone as much as the type of wood used. Also, it is important to note than more than one wood may be used in a single instrument. For example, it is not uncommon for the top to be made from a different type of wood than the back and sides. This may be done to create a well-rounded tone or lower the total cost of the instrument.
Mahogany is one of the most common wood uses in guitar and ukulele. They are use as top, back, and sides. Mahogany is medium dense hardness, easy to bend and to work with. Finish Mahogany showed beautiful brown color. They offer dynamic response and mid-range. You will experience warm low end.
The tone and wood figures of Koa is what people love. They are use in top, back, and sides. Koa is rare, and expensive. Koa is similar to Mahogany with nice mid-range. Koa is denser wood, so you will get a brighter attack, and sweet high. The tone will mature and grow as you play in the musical instrument.
Sitka has perfect straight grain which is great for making musical instrument. It has great strength, and elastic allow greater movement on the top. They yield that crispy high, and articulation. It is great of fingerstyle, and strumming.
Ukuleles can be built with laminated or solid wood tops. A solid wood top is made from a single piece, while laminates use multiple layers stacked together. Laminate tops tend to be less expensive and are also highly durable. The use of multiple layers helps the wood resist warping over time, which holds the body together and keeps the instrument's sound stable over time. However, laminate-top ukuleles cannot always produce the same richness of tone as their solid wood counterparts. In contrast, the feel and tone of a well-built solid wood ukulele can improve with time and use.
