Seeking to provide guitarists and bassists 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.
Patent pending.

My New Preferred Stings - Ernie Ball Cobalts


Tried these out for the first time. I usually play on the standard slinkies, but I read up on the Cobalt strings and they seem to have a lot of popularity, so I wanted to try them out myself. I am 15 year guitar player, currently using a Fender Strat. These strings might be my favorite I've ever used. Their tone and resonance is very distinct and graceful. And, of course, you're using Ernie Ball strings - so the slide and flexibility of the strings are unmatched. Overall, I would highly recommend for anyone using a mid-to-high tier grade guitar.



Love the tone of cobalt


Sound great, really durable

Super loud strings, kind of resembles a Clapton boost honestly. I love these strings. Use them on my Telecaster and they just cut! *Hands on review by Christopher M. from store 57 in Indianapolis.
