Ernie Ball 7-String Regular Slinky Cobalt Electric Guitar Strings, 10-56 Gauge (P02728)
- Ernie Ball 2721 Cobalt Regular Slinky Electric Guitar Strings are a new spin on Ernie Ball's best selling set of strings which have been played by the likes of Eric Clapton, John Mayer, Steve Vai and many more.
- 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.
- "Ernie Ball Cobalt Strings sound and feel better than anything I've ever played! You have to check these out!" - Slash.
