A tool to tighten loose guitar jack plugs without getting inside your instrument.
This Jack and Ferrule tool offers a quick and easy way to tighten a loose jack plug on any surface-mounted input. Just insert the tool into the jack and use the Allen wrench to tighten the internal, hexagonal-head, set screw. This gives the holding power needed to tighten the retainer nut without having to go inside the instrument. This tool also works great for removing 1/4" string ferrules.
A must-have guitar tool for luthiers!

Comments about String Swing Guitar Jack and Ferrule Tool:
Simple, solid brass tool does exactly what it needs to do, and does it well. I needed a tool that would allow me to tighten the ring on a strap jack, and some of the other tools limit their use to tightening a hex nut. With this tool you can use whatever tightening tool is required. After several attempts to tighten the strap jack using other on-hand tools, this allowed me to do the job in 5 minutes. This tool should last me as long as my fingers still move.
