The most common setup need on acoustic guitars is the truss rod but adjustment nuts aren't necessarily easy to get to, particularly if accessed through the sound hole. Central to Tech Kit is a clever locking bit driver that allows for quick interchange of bits, with special bits for both sound hole and headstock truss rod adjustment.

Also included are tech kit staples such as thickness gauge and capo for relief measurement, screwdriver bits, string winder, our highly-rated GrooveTech String Cutters, and a telescopic mirror in case you need to have a look inside remote cavities of the body.
