StewMac 2-in-1 Precision Notched Straightedge for Long Scale

In this review the StewMac 2-in-1 Precision + Notched Straightedge is presented as a practical, workshop-grade tool for luthiers and serious players who demand repeatable neck setups. The bottom line is simple: this American-made dual-sided straightedge combines a plain precision edge and a notched edge sized for long scale guitars, making it the fastest way to check fingerboard flatness and quickly measure neck relief for Gibson, Fender and Martin scale lengths. It is aimed at technicians who need a dead-flat reference and want two professional tools in one.

Key Features

• American-made build: Crafted in Ohio, it offers a reliable, rigid reference edge that stands up to workshop use.
• Dual-sided design: One side is a plain precision straightedge and the other is notched to sit over strings for quicker relief measurements.
• Long scale compatibility: Notches and markings accommodate Gibson 25.3in, Fender 25.5in and Martin 25.4in scale lengths for accurate checks.
• Fingerboard flatness checking: The dead-flat edge lets a tech detect tiny high or low spots that can cause buzz or fret problems.
• Fast neck relief measurement: The notched side speeds up routine setups so adjustments and truss rod turns are more efficient.

Who It's For

The tool is aimed at instrument technicians, independent luthiers and serious hobbyists who perform setup, fret dressing or build work and need reliable, repeatable reference edges. If you frequently switch between Gibson, Fender and Martin long-scale instruments, the notched side removes guesswork and saves time during relief checks.

Players who only perform very occasional basic adjustments and prefer cheaper multi-tools might look elsewhere; this straightedge is best suited to users who value a precision, dead-flat surface and American workmanship rather than a low-cost disposable item.

Pros & Cons
