Having the right tool to perform your key gear adjustments is essential. MusicNomad’s 4mm Truss Rod Wrench is the perfect tool for adjusting Truss Rods that are located deeper in the soundhole. Our durable steel construction with a black nickel finish is designed to work over and over again. The 4.75” long arm combined with the ball end design allows you to adjust Truss Rods found on popular acoustic guitars that use a 4mm nut, such as  MARTIN® Guitar models DSS, OMSS, Modern Deluxe Series and SC-13E. The ergonomic handle provides extra length, comfort and control, making turning easier. That’s MusicNomad quality – raising the bar in equipment care.
