Using your Fender Festival Instrument Cable is a breeze. Just plug one end (the 1/4 in. Right Angle) into your instrument and the other end (the 1/4 in. Straight) into your amplifier or audio device. When handling the cable, be gentle to avoid bending it too sharply, as this could damage the internal conductors. For storage, you can coil it up neatly, but don't make the coils too tight. To keep it in great shape, wipe it down with a dry, soft cloth regularly. If it gets dirty, you can use a slightly damp cloth, but make sure to dry it thoroughly afterwards. And always unplug the cable properly to avoid any electrical issues.
