Description
Ernie Ball’s Cobalt series marks a genuine shift in wrap wire chemistry, moving beyond traditional nickel and steel to a cobalt-iron alloy that reacts more strongly with magnetic pickups. That closer string-to-pickup relationship translates into a fuller signal reaching your amp, with more pronounced low end, articulate top end, and a wider overall dynamic window than conventional string alloys typically offer.
Players who dig into dynamics will notice the difference most: pick softly and the Cobalt Extra Slinky set stays clear and detailed, dig in harder and it pushes back with added punch and harmonic complexity. The cobalt wrap also has a notably smooth, silky feel under the fingers, which makes bends, slides, and vibrato feel more fluid on the fretboard.
This is the Extra Slinky gauge set (.008-.011-.014-.022-.030-.038), a lighter configuration favored by players who want easy bending and a fast, low-tension feel without sacrificing tone. Each pack is a single set of six strings.
