Tool - GrooveTech, Jack / Pot Tool
Instrument and amp jacks are notorious for coming loose. And with a shallow nut and recessed cavity, access can be challenging. Until now, that is. The GrooveTech Jack and Pot Wrench provides three thin-wall sockets - ½", 7/16", and 12mm - in a compact four-inch tool to handle the most common sizes of jacks and pots on instruments, amps, and other audio gear. Add a dab of threadlocker, and you'll probably never have to deal with that loose jack again. Sockets are pro-grade with a dazzling polished chrome finish.
