Ernie Ball Cobalt bass strings are crafted from a revolutionary alloy formulation that significantly enhances your playing experience by providing higher output, superior sound quality, and impressive longevity. The unique iron and cobalt blend used in these strings is specifically designed to attract the magnets in your pickups more effectively than any other alloy available on the market. When you install a set of Ernie Ball Cobalt strings, you'll immediately be struck by the remarkable comfort they deliver. Their silky texture and pliable design allow for effortless movement under your fretting fingers, enabling you to execute fast passages and intricate techniques with ease. When it comes to sound, Sweetwater bassists have found Cobalt strings yield powerful sonics characterized by robust yet well-defined low frequencies, enhanced midrange clarity, rich harmonics, and sustained crisp highs. Experience the difference for yourself by trying a set of Ernie Ball Cobalt bass strings — the exceptional quality and performance are sure to elevate your playing to new heights!

Note: Given their length, Cobalt strings are not compatible with some top-loading P Bass instruments. Please contact your Sweetwater Sales Engineer if you have any questions.

Ernie Ball: championing string design since 1962

When Ernie Ball released his first set of Rock N Roll guitar strings in 1962, the goal was simple: to provide custom string sets for newcomer musicians and gauge-particular players. Little did he know that this mindset would lead to further innovation and diversification, with not only electric guitar string sets but also strings for bass and acoustic guitar. By the turn of the century, Ernie Ball’s unwavering commitment to contemporary musicians resulted in the introduction of several new string series. Notable among these were Ernie Ball’s acoustic Earthwood strings and the widely popular Slinky family of strings. Today, Ernie Ball strings maintain their iconic status as a go-to choice for guitarists and bassists worldwide, and for good reason. Built to maintain stable performance, tone, and comfort in the face of any playing situation, a fresh pack of Ernie Ball strings doesn’t just guarantee great tone — it symbolizes a legacy of musical innovation and creativity.

Ernie Ball Regular Slinky Cobalt Bass Strings Features:

  • Punchy, high-output strings with a powerful sound that cuts through any mix
  • Resonant low end with increased presence and growl
