GrooveTech GTTRS1 Truss Rod Driver

I purchased thisdevice after many years of doing repairs on vintage instruments and being unable to find the right tool to do the job with any satisfaction . This driver meets all requirements and expectations . If you have avintage instrument or areissue , I would hihgly recommend this device . Fantastic . bfn Dex V .!

Spent years trying to adjust my Jazz Bass CIJ '62 RI truss rod, clamping & lubricants, no luck. This tool had enough torque to turn the heel nut on the second attempt & saved me the expensive cost of taking the Bass to a Luthier. 100% recommended.
