Key Features

  • Authentic Martin-Style Design – Engineered specifically for traditional acoustic guitar construction with heel-end adjustment.
  • Hybrid Construction – Combines the lightweight rigidity of an aluminium U-channel with the tensile strength of a steel rod.
  • Protective Installation Feature – Comes with masking tape applied to prevent epoxy from entering the mechanism during gluing.
  • Complete Hardware Included – Comes with adjustment nut and washer ready for installation.
  • Optimized Weight & Strength – Provides essential neck reinforcement without adding unnecessary mass.
  • Precision Manufacturing – Made in Japan to exacting standards for consistent quality and performance.

Why Choose the Hosco U-Channel Truss Rod?

  • Traditional construction for authentic Martin-style builds and repairs.
  • Builder-friendly design with protective features that prevent installation errors.
  • Proven reliability in both professional luthier and DIY applications.
  • Maintains vintage-appropriate adjustment methods while using modern materials.

Installation Note: Install into a flat-bottom channel with the flat side of the U-channel facing up. Secure with a thin line of epoxy on the sides—do not remove the protective masking tape. Ensure no glue enters the truss rod channel when installing the fretboard.
