Machine Head

A machine head (also referred to as a tuner, or gear head) is a geared apparatus for tuning stringed musical instruments by adjusting string tension. Machine heads are used on mandolins, guitars, double basses etc., and are usually located on the instrument's headstock. Non-geared tuning devices that are used on violins, violas, cellos, lutes, older Flamenco guitars, ukuleles etc., are known as tuning pegs.
