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.

Famous quotes containing the words machine and/or head:

    One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.
    Elbert Hubbard (1856–1915)

    Thus Satan talking to his neerest Mate
    With Head up-lift above the wave, and Eyes
    That sparkling blaz’d, his other Parts besides
    Prone on the Flood, extended long and large
    Lay floating many a rood, in bulk as huge
    As whom the Fables name of monstrous size,
    Titanian, or Earth-born, that warr’d on Jove,
    Briarios or Typhon, whom the Den
    By ancient Tarsus held, or that Sea-beast
    Leviathan,
    John Milton (1608–1674)
