The 13-in-1 Multi-tool from RockCare features string winders for guitar and bass. The blue, inch version (pictured) of the tool features imperial hex-wrenches and a truss rod wrench for instruments from the U.S. It combines all necessary tools for guitar and bass in a compact form, and string winders can be attached and easily exchanged if need be. Fold-out tools are safely accommodated in both housing halves and fixed in the end position with the closed cover. A built-in string cutter easily cuts through all common string gauges. A red, metric version is also available.
