Finely tunable guitars
Using a tool the tip of which fits exactly into the groove, you can press the fret elements into the fingerboard or remove them and, depending on the desired pitch of the note, slide them up and down. To help you, you can either use a tuning device or simply do it by ear. The frets can be adapted to suit the curved fingerboards of electric guitars, violins, cellos and double basses.
