The loudest, most expressive strings ever created providing increased output, frequency response, and strength.

M-Steel, short for Maraging Steel, is a super alloy used in high stress applications for the aerospace and defence 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.
