D'Addario Custom series wires can handle significant wear and tear, making them perfect for amplifying your front ensemble or giving some juice to quiet acoustic instruments at a gig. They offer low capacitance (resistance against electronic signals, making you lose high frequencies over cable distance), oxygen-free copper conductors, and double-molded strain relief. All of this technical jargon means that they can handle some road trauma and still sound fine. They also feature two layers of shielding to further keep your signal pure.
