Using this Fender instrument cable is easy. Just connect it between your musical instrument and amplifier or other audio devices. Before using it in a dark environment, make sure to leave it in natural light or sunlight for a few hours. This will give you 2 - 3 hours of a bright glow. When handling the cable, try to avoid sharp bends and excessive pulling to prevent kinking. After each use, gently coil the cable and store it in a dry place. If it gets dirty, you can wipe it with a soft, dry cloth.
