The Fret Level, Crown, and Polishing class takes the student through the three parts of fret levelling. First, frets will be worked level and confirmed as such by both teacher and student. This is followed with meticulous filing of the top of each fret to establish the ‘ crown ‘or center of the fret which is very important for intonation and general playability. Finally, the frets will go through a polishing process to ensure a playing surface free of any machining abrasions. Also, a set of fret leveling tools will be made for the student to keep.
