The headstock is a crucial part of stringed instruments, such as guitars and violins. It is located at the end of the neck and houses the tuning pegs, which are used to adjust the tension of the strings. This adjustment affects the pitch of the notes produced by the instrument. In addition to tuning pegs, the headstock often features a nut, which helps guide the strings to the fretboard. The design and shape of the headstock can vary significantly between different types of instruments, including electric guitars and acoustic guitars, influencing both aesthetics and functionality.
