Independent shopping perspective
The Korena take
The 2728 Cobalt Regular Slinky set brings .010–.056 gauges to a 7-string guitar in standard tuning. Its Cobalt construction is designed to increase the magnetic interaction between strings and pickups, with more output, a wider dynamic range, harmonic response, stronger lows, and clear highs. The set is presented for contemporary rock and metal work, covering chunky rhythm parts and fast lead playing. Ernie Ball also describes the strings as soft and pliable for wide bends and complex techniques.
