This handy professional-grade tool offers easy access to acoustic truss rod nuts located inside the sound hole. The GrooveTech Sound Hole Truss Rod Driver allows you to quickly adjust the truss rod of your acoustic guitars—even if the nut is tucked away inside the sound hole. Acoustic guitar truss rods need adjustment just like electrics, but manufacturers sure don't make it easy. This handy professional-grade tool features a long right-angle shaft that can reach into sound holes with a precision ball-end tip for easy fit, extra length on both segments of the blade, and an oversized handle for confident control when making adjustments. Professional-grade.
