Plek Optimization

The Plek machine is a computer-controlled alternative to traditional methods of manual fret dressing.

The machine records the fret height in relation to the fretboard surface beneath each string at each fret to the accuracy of .0004”. After recording each measurement,  the machine then grinds each fret to proper heights, eliminating buzzing and improving overall playability.
