Newly updated, we managed to sequeeze even more function into this highly competent multi-tool. Like before, there's both inch and metric hex wrenches for USA and offshore produced guitars and basses, but with two sizes added. Truss rod sizes are ball-end for easy access. A 5/16" nut driver handles Gibson truss rod nuts, and a ruler permits precise measurement prior to adjustment. Also included are two slotted Phillips screwdrivers and a 2.5mm slotted scewdriver for vintage-style saddle screws. The one-piece body allows easy rotation and storage of all components. All keys are pro-grade, using heat-treated S2 material with a polished chrome finish.
