Product Information

Ernie Ball's Cobalt Not Even Slinky 12–56 gauge set delivers substantial low–end heft without sacrificing playability. Cobalt alloy wire produces a stronger magnetic response with pickups than conventional nickel, translating to higher output, extended dynamic range, and articulate harmonic reproduction across the frequency spectrum. The heavier gauges suit drop tunings, extended–range instruments, and players chasing punchy, defined tone through high–gain amplification.

The 12–56 configuration pairs a .012" high E with corresponding gauges of .016", .024", .032", .044", and .056". Despite the increased mass, these strings employ a windings technique that preserves flexibility, making string bending and vibrato accessible without hand fatigue. The cobalt composition enhances sustain and clarity in both rhythm and lead applications, whilst the heavier gauges provide superior tension stability on instruments with longer scale lengths or aggressive playing dynamics.

Players gravitating towards alternative tunings–drop D, drop C, or lower–will find the Not Even Slinky set maintains intonation precision and harmonic integrity. The combination of cobalt's magnetic properties and heavier gauge construction creates a tonal platform suited equally to studio tracking and touring rigs where consistency and articulation demand priority.
