EB 2921 M-Steel Regular Slinky

The loudest, most expressive strings ever created. Provides 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.
