From adjusting your guitar's truss rod to intonating its saddles and setting the height of your action, the GrooveTech Guitar/Bass Multi-tool is a guitarist's best friend (if you value maintaining your instrument, that is). It offers a range of metric and inch hex keys, three screwdrivers, and truss wrenches with ball ends for easier insertion. All this is packed into a compact 1-piece body that is surprisingly easy to rotate (compared to some other multi-tools).
