Abstract
A high density headplate (12) made of brass or other metal is secured between a stringed instrument's headstock (10) and its tuning machine (20). This both increases the angle (A) of the string (14) at the nut (16) and effectively increases the density of the headstock which results in a noticeable increase in sustain as well as an improvement in the perceived frequency response of the instrument.
