StewMac Precision Fret Guitar Tool Trio - Essential Setup Tools

Our review of the StewMac Precision Fret Guitar Tool Trio finds it ideal for players and techs who want a small, reliable kit for diagnosing and fixing fret and action problems. The set combines a String Action Gauge, a 4-in-1 Fret Rocker and a targeted Fret Kisser, giving a complete toolkit for measuring string height, spotting high frets and performing spot leveling without removing or reshaping entire fretboards. For home setups and workshop use alike, its durability and precision are the single biggest reasons to buy.

Key Features

• Complete kit: Includes a String Action Gauge, Fret Rocker and Fret Kisser for a full diagnostic and repair workflow without needing extra parts.
• Accurate string action: The String Action Gauge measures string height, nut and saddle settings and pickup height with precise, instrument-specific graduations for consistent setups.
• Fret rocker precision: The 4-in-1 mini straightedge identifies high frets across different scale lengths so you can detect fret buzz and uneven frets quickly.
• Spot leveling efficiency: The Fret Kisser lets you target single high frets, saving time by avoiding filing the whole fretboard for isolated issues.
• Built to last: High-quality construction trusted by luthiers and repair techs promises long-term performance in both shop and home settings.
• Support included: Backed by expert tech support, including professional luthiers, for setup and troubleshooting questions.

Who It's For

The kit suits guitarists who perform their own setups, hobbyist luthiers and techs who need compact, accurate measuring and leveling tools. Its combination of gauge, rocker and kisser covers the common tasks of measuring action, locating high frets and performing targeted fret work, making it useful for electric and acoustic guitar maintenance.

Players who only need basic accessories, or who prefer full board leveling with power tools, might look elsewhere; this trio excels at precision hand work and diagnostic checks rather than rapid bulk fret dressing.
