Description

Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky Guitar Strings are the latest innovation in string technology. 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.

  • Great tone
This is subjective, but I love the tone of these Cobalt strings. About the only downside *may* be a coincidence, in that it seems like my high e-string breaks slightly more frequently / easily than a regular steel or nickel string. But even if that's the case, it's worth it.

  • Great tone and feel for overdriven tube sounds
After trying different strings, including others by Ernie Ball, these are my clear favorite for playing with an overdriven tube sound. The cobalt in the low E, A, and D strings produces a biting thick sound with overtones that also feels good under the finger ("slinky" is actually a good description I think) when sliding, bending, or adding vibrato. ... show more

Bought for my dad as a birthday present - he's never had cobalt strings before and wanted to try. They sound very smooth and he likes the tone of them! I even got the package earlier than expected - arrived on a Friday when expected the next Monday!

This is the first time that I have tried the Cobalt Strings..... Personally, I LIKE them. Bright but not too tangy. I will buy again.
