Made of Ernie Ball's patented M-Steel alloy, these strings produce a robust tone with crisp highs, thick lows, and harmonically rich overtones. The M-Steel hex core and Super Cobalt windings are specifically engineered for higher output and definition, allowing your tone to cut through any mix. For over 50 years, Ernie Ball strings have been the choice of musicians looking to unlock their instrument's full potential. The 2921 M-Steel Regular Slinky strings continue this legacy of performance and innovation.

M-Steel Hex Core Wire Provides Ultra-Stable Tension

At the heart of the 2921 strings is a maraging steel hex core wire that provides maximum tensile strength and tuning stability. Maraging steel, used in high-stress applications like aircraft parts, allows for a thinner core gauge without sacrificing durability. This results in a string that has enhanced flexibility and reduced mass, producing a clear tone with full-bodied overtones and crisp articulation.

Super Cobalt Windings Add Output and Clarity

Ernie Ball's patented Super Cobalt alloy is wrapped around the maraging steel core to create windings that significantly boost the strings' output while accentuating pick attack and harmonic content. Super Cobalt's magnetic properties translate the energy of your pickups into a powerful tone with rich overtones and clear, singing highs. These windings are designed to bring out the best in high-gain amplifiers and overdrive pedals.

Fine-Tuned Gages For Balanced Tension and Feel

The 2921 M-Steel Regular Slinky strings are precision engineered with gauges of .010, .013, .017, .026, .036, and .046. This combination produces evenly balanced tension and an familiar playing feel for most electric guitars. The lighter top strings facilitate complex chords and leads, while the heavier bottom strings provide a solid low end foundation. Overall, these gauges translate into a versatile set of strings suitable for everything from rock and blues to metal and jazz.

Built to Perform and Last

Like all Ernie Ball strings, the 2921 M-Steel Regular Slinky strings are constructed using the finest materials and manufacturing techniques to ensure maximum performance, longevity, and reliability. The precisely tempered steel alloys and high-quality winding processes result in strings that stay in tune, maintain their tone, and avoid premature breakage gig after gig. For strings that can keep up with your playing, you can't go wrong with Ernie Ball.
