Guitar neck and Fret board
The guitar neck itself is most commonly made out of rosewood or maple or variations of those types of wood. Necks can also be made out of ebony or mahogany.
Some players choose their guitar necks carefully as it is a factor in the overall sound of the guitar.
The neck is either bolted to the guitar body or made as one part with the guitar body.
