The loudest, most expressive strings ever created providing increased output, frequency response, and strength. M-Steel, short for Maraging Steel, is a superalloy used in high stress applications for the aerospace and defense industries. The wound strings are comprised of a patented Super Cobalt alloy wrapped around a Maraging steel hex core wire, producing a richer and fuller tone with powerful low end response. M-Steel plain strings are comprised of a specially tempered steel for maximum fatigue resistance. A patented winding of steel around the ball end of the plain strings reduces slippage, breakage and stays in tune better than conventional plain strings. Power Slinky electric strings are a perfect match for those who like chunky rhythms for rock and roll or blues. Gauges .011, .014, .018p, .028, .038, .048
