Dunlop Zakk Wylde Incon Series Custom Electric Guitar Strings were developed to withstand the punishment of the reigning king of metal guitar. Extensive engineering and critical road testing by Zakk himself perfected an electric guitar string formula to work under the heaviest hands in rock. Zakk Wylde Signature Strings were designed around Dunlop High Tension technology with a bulked-up core wire for less breakage, long-life, and better definition and pitch retention at lowered tunings. Gauges .010, .013, .017, .036, .052, .060
