ABSTRACT:
An inventive positioner adapted to secure a string of a guitar or other fretted stringed instrument at fret positions in order to quickly and easily vary the length of the string available for vibration to change the pitch when the string is plucked. The positioner describes a threaded machine screw received in a metal insert, the insert fixedly held in the fretboard of the neck of the guitar. The positioner screw is angled at a preferred 55.degree. angle with respect to the fretboard and so positioned that it hooks the string in a locking downward "V" catch to secure holding the string against the fretboard so that the string will rise up and engage the adjacent fret between the positioner and the guitar main body. The guitar string is not moved laterally when it is engaged and held.
A plurality of positioners are provided for each of the guitar strings behind each fret throughout the length of the fretboard in order that each guitar string effective vibrating length may be changed as desired. After use, the positioner is unscrewed to release the guitar string.
