For the latest technology in electric guitar strings, you must try the Ernie Cobalt Guitar Strings from Strings and Beyond. Manufactured to maximize clarity and output, Ernie Ball Cobalt Slinky Guitar Strings are the most recent breakthrough in guitar string technology. Cobalt guitar strings provide a newly extended dynamic range, great harmonic response, increased low end and brilliant highs. That is why they are giving guitarists and bassists new horizons to explore. Cobalt strings are built with a better magnetic relationship between pickups and strings than any other alloy made in the past. The Cobalt Slinkys are soft to the touch, which makes string bending easier than ever. The Cobalt Series is a vast improvement over its nickel-wound competitor because its strings provide better sustain and clarity in the sound. They also are sweat and moisture-resistant while being flexible and long-lasting.
