The Ernie Ball Electric Guitar String Tone Pack is the perfect way to experience three legendary electric guitar tones. From the world's #1-selling Original Slinky strings, featuring classic, balanced tone, or the Cobalt Slinky Strings, providing higher output and superior clarity, to the M-Steel Slinky strings, which are the loudest, most expressive strings ever created. Three tones. One pack. Famously slinky.

SLINKY
Ernie Ball Slinky Electric Strings are Ernie Ball’s top-selling set, and are favored by many musicians around the globe. Slinky strings are played by Eric Clapton, John Mayer, Steve Vai and legions of guitar players worldwide. These strings are precision manufactured to the highest standards and most exacting specifications to ensure consistency, optimum performance, and long life. Slinky wound strings are made from nickel plated steel wire wrapped around a hex shaped steel core wire. The plain strings are made of specially tempered tin plated high carbon steel producing a well balanced tone for your guitar.

COBALT
Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky Guitar Strings are among the latest innovations in string technology. Seeking to provide guitarists with a new voice, Cobalt strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs. Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy previously available. Cobalt Slinkys are also soft and silky to the touch, making string bending a breeze.

M-STEEL
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.
