D’Addario is proud to introduce Jack Plugs: a fast, effective way to block unused ¼" jacks on pedals, amps, and audio gear. Touring guitarists, studio engineers, and live sound techs alike can prevent accidental connections, speed up the rig set up process, and protect their gear from dust, debris, and interference. Even better, installing these small, easy-to-use accessories is simple and requires no tools, minimum hassle, and no cleanup.
