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. Metal fans worldwide have gravitated towards the Beefy Slinky set to give their guitar the optimal gauge combination for Drop D and Drop C tuning. 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. Cobalt is the most magnetically active string alloy on the planet and attracts the magnets in your pickups more than any other string.

"Ernie Ball Cobalt Strings sound and feel better than anything I've ever played! You have to check these out!" - Slash.

All Ernie Ball strings are precision manufactured to the highest standards and the most exacting specs to assure consistency, optimum performance and long life. Made in the USA.

Gauges: 11-15-22p-30-42-54.
