The Yamaha C40 Black is a full-size guitar, which means it is the classic full-size guitar for adult players (4/4 size). The spruce top of this classical guitar rests on a body made of meranti, a type of hardwood native to Southeast Asia. The neck is made of nato, a mahogany-like wood, and carries a rosewood fingerboard. The chrome-plated tuners allow the guitar to be tuned precisely and quickly.
