Try the new and improved strings ideal for drop tuning.

Ernie Ball Cobalt Beefy Slinky Electric Guitar Strings are perfect for those who like to detune their instrument to lower tuning combinations.

The Cobalt Series is clearly an improvement on its classic nickel-wound counterpart giving the player increased sustain, clarity and output. In addition, they resist sweat and moisture better and have unmatched flexibility when compared to other nickel wound strings.

    Comments about Ernie Ball 2727 Cobalt Beefy Slinky Electric Guitar Strings:

    I bought these because I play heavier guage. I was hoping to get a wound G. I feel @ .30 guage you need one?
    I like the clarity of these strings - they seem to settle in fast and last too.
    Otherwise - they're strings. What more do you want?
