Ernie Ball 2729 Power Slinky 7-String

7-string electric guitar strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs. Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy previously available. Cobalt Slinky guitar strings are also soft and silky to the touch, making string bending a breeze. Gauges: .011, .014, .018, .028, .038, .048, .058
