Fretboard Prep Tool – Heavy Duty
For luthiers who want the cleanest possible fretwork—with feel and finish to match
Why this matters
Before you start shaping semi-hemi fret ends, your fret installation has to be near perfect—frets seated so well, they don’t need levelling afterward.
That’s exactly what Michael Bashkin teaches in his fretting course with Robbie O’Brien: careful prep, precise installation, and how to finish frets by hand.
Since filming that course, Michael added this tool to his bench. It sped things up without sacrificing precision.
