Independent shopping perspective

The Korena take

Cobalt Regular Slinky is a three-pack of electric-guitar sets built around cobalt alloy wrap wire. The .010–.046 Regular Slinky gauge range provides the familiar set format named in the title, while the cobalt wrap is designed for a strong magnetic relationship with guitar pickups. The result described for the set is extended tonal range, clearer definition, increased output, and added sustain. Buy it when you want to keep the same cobalt-wound electric set available for repeat restringing.
