ABSTRACT:
A finger operated locking nut assembly for a stringed instrument is provided including a baseplate for separating and maintaining the strings over the fretboard, a locking block for pressing the strings against the baseplate and a cam action lock screw. The lock screw provides a first, unlocked position for allowing the strings to slide for tuning of the instrument and a second, locked position for maintaining the tune of the instrument during play. The preferred lock screw includes a threaded body to allow rough adjustment and a transverse head bifurcating a pivoting lever tab to define spaced cams. These cams provide spaced contact points across the block for even pressure and secure locking of the strings.
