This is a guitar cable from D'Addario PLANET WAVES. I've only used it at home. It's a mid-range cable, and I bought a more expensive one soon after, so it's been stored away for over a decade. I have checked that it works. Features: Due to its two-core structure designed to reduce noise, the connection direction is fixed. The connection direction is indicated by guitar and speaker markings on the connectors. To prevent poor contact between the jack and plug, the base of the jack is expanded to provide a secure hold. There are four colors of rings attached to the jack, and they can be replaced. *Some of the colored rings are missing. Please understand.
