MusicNomad Premium Truss Rod Wrench 4mm for Martin Guitars
MusicNomad's Premium 4mm Truss Rod Wrench is engineered specifically for adjusting acoustic guitar truss rods recessed deep within the soundhole. Built from durable steel with a black nickel finish, this dedicated tool delivers long-lasting reliability and precision for routine neck adjustments.
Featuring a 4.75-inch long reach arm and a specialized ball-end design, it provides easy access and engagement at an angle for standard 4mm nuts. It is compatible with select Martin guitar models including the DSS, OMSS, Modern Deluxe Series, and SC-13E, as well as other acoustic instruments requiring a 4mm soundhole wrench.
An ergonomic comfort handle offers extended reach, optimal leverage, and superior turning control during setup. The 4mm size is permanently laser-etched into the metal arm for quick and foolproof tool identification in any guitar maintenance kit.
