Using this D'Addario instrument cable is easy. Just plug one end into your instrument and the other end into your amplifier or audio device. When using, make sure the plugs are firmly inserted to avoid signal interruption. Don't yank the cable out forcefully as it may damage the plugs. For maintenance, keep the cable away from sharp objects to prevent cuts. You can clean it with a soft, dry cloth occasionally. Store it in a cool, dry place when not in use to prolong its lifespan.
