Ernie Ball M-Steel Super Slinky Electric Guitar Strings 9-42

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
