Thanks to the Music Nomad The Octopus 8 in 1 Tech Tool, lugging around a bunch of screwdrivers and spanners is a thing of the past. Music Nomad's innovative design is perfect for tightening or loosening output connectors, belt locks, control pots, sockets and voting machine screws. It includes both a clean-head screwdriver and a flathead screwdriver. With its reversible design, there is a special design on the other side of the tool with popular sizes of hex keys: 10mm, 12mm and 14mm. Either way, this tool is a must-have for every guitar case!
