Maple wood is the most commonly used wood in guitar necks. Maple is a strong wood able to withstand the hardship of guitar use. It is suitably tough to keep the strings in tune and provides a sharp, focused tone. A maple guitar neck also has a uniform grain that suits the requirements of a guitar very well.
Straightness of the wood is of primary importance. If you have a bowed neck there will be uneven spacing between the frets and strings. This will cause you many difficulties when playing the guitar; throwing out the sound quality. The more popular woods chosen for guitars are rosewood and mahogany.
These hardwoods offer stable necks and provide you different tonal preferences. Mahogany produces a warm, full tone with an emphasis on the highs. Rosewood has clarity in the bottom end and sparkle in the top range of tones. Other woods you can select from all offering a unique tone include: alder, poplar, basswood, maple, red spruce, sitka, spruce, Indian, rosewood, Brazilian rosewood, koa, mahogany and ebony.
As you develop a honed and discerning ear to the different sounds a particular wood provides you will become more critical and 
discerning about what guitar is right for you. The love and care you put into your songs should also be reflected in the selection of your instruments.
Your songs won’t find their voice unless your instruments are carefully chosen to compliment them. As you develop an ear for the different qualities of the tones and are able distinguish the frequencies a particular wood provides, the more comfortable you will be with your instrument and the better music you will play.
