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 the instrument's brand or logo. It can come in various shapes and designs, contributing to the overall aesthetic of the instrument. The headstock plays a vital role in both the functionality and appearance of instruments like guitars and basses.
