Abstract
A string locking assembly is provided for mounting on the headstock of a guitar or the like between a string nut and tuning pegs. The assembly includes a baseplate that is mounted directly to the headstock. The baseplate includes an outwardly disposed surface for supporting the guitar strings and outwardly extending posts at spaced intervals. The posts separate the individual strings and are sufficiently spaced to allow a wide range of string spacings to pass from the string nut to the tuning pegs through the assembly without interference. The assembly also includes a locking block overlying the strings and the baseplate and an associated cam action lock screw. The lock screw provides an unlocked position to allow quick tuning of the guitar and a locked position to provide clamping pressure between the locking block and the baseplate so as to prevent slippage of the strings over the string nut during play.
