Innovative tools for optimum setup

GMC Luthier Tools Universal Notched Edge shown checking an 8-string guitar.

Notched straight edges

Designed to assess the exact portion of the fretboard that flexes under truss rod adjustments. By excluding the rigid upper frets past the neck heel, the universal notch layout fits any scale length within the tool's range.

GMC Luthier Tools String Action & Setup Gauges. Full set of 5-gauges laid out in a fanned shape.

String action gauges

A unique system that uses compensated radius contact to set string action, pickup heights and bridge saddles to match the fretboard radius.
