The Korena take
Ernie Ball 2729 Cobalt 7-String Power Slinky strings are an electric-guitar set from the Cobalt Slinky series. Their cobalt alloy is designed to maximize output and clarity, with extended dynamic range, strong harmonic response, increased low end, and clear highs. The material is described as especially magnetically active toward pickup magnets. In hand, the strings are presented as soft and silky, with bending made easier by that feel. This set is specifically identified for seven-string electric guitar.
