MusicNomad MN840 Precision Fret Gauge Ferramenta para guitarra

Diagnose Fret Problems Before They Get Worse

The MusicNomad MN840 Precision Fret Gauge is a pocket-sized diagnostic tool that helps players evaluate fret condition on electric, acoustic, classical, and bass guitars. Uneven or unseated frets cause buzzing, choking notes, and stiff action — this gauge checks four key conditions: fret level, fret seating, fret height, and fret size. Stainless steel feeler gauges are oil-free, so they won't stain the fretboard during inspection.

What Sets This Gauge Apart

Unlike traditional feeler gauge sets coated in messy protective oil, the MN840 uses clean stainless steel with laser-etched markings in inches and millimeters that won't rub off over time. Instructions are printed directly on the handle, and a hang hole keeps storage simple. Pair it with the MusicNomad MN822 Precision Fret Rocker+ (sold separately) for a complete fret evaluation workflow.
