The Korena take
Built for a 7-string electric guitar, this 10–62 Cobalt set pairs lighter upper strings with heavier lower strings. The cobalt alloy is designed for a stronger pickup response, extended dynamic range, harmonic detail, defined lows, and crisp highs. Its smooth surface and flexible core support slides, vibrato, bends, and detailed lead work, while the heavier bottom end is voiced for thick distorted parts. Ernie Ball also states that Cobalt keeps its brightness and clarity up to four times longer than traditional strings.
Strong match
Who this is for
