Tuning Pegs: There are six tuning machines or heads, arranged in a standard 3-a-side configuration, which are used to adjust the tension and pitch of the strings.
Material and Design: The headstock appears to be made of wood, consistent with many acoustic guitars. Standard acoustic guitar headstocks are often angled at an angle to the neck for optimal stability and string tension.
Function: The machine heads on the headstock allow the instrument to be tuned by adjusting string tension.
