Fret Polishing: Faster, Cleaner, Without Masking
The MusicNomad MN803 "Fret Shield" is a patented stainless steel protector designed for the maintenance and polishing of frets on instruments with a 643 mm scale length and 20 frets. In just a few seconds, it positions itself on the fretboard and allows you to work cleanly with polishing pads, polishing discs, or any other system, while reducing the risk of micro-scratches and avoiding the hassle of masking. Its conical shape and calibrated slots ensure wide compatibility, from narrow to jumbo fret profiles, on 6- or 7-string guitars, without damaging the finish.
