Hybrid Slinky Cobalt Strings for Electric Guitar!

The development goal was maximum output and clarity. The Ernie Ball Slinky Cobalt strings are the latest advance in string technology and give the instrument a new voice.

Cobalt is more magnetic than nickel, so these strings deliver maximum output, greater dynamics, more harmonic resonance, full-bodied lows and crisp highs. Because cobalt is tougher than nickel, Ernie Ball Cobalt strings are more durable than conventional strings.

The soft, silky feel makes string bending a breeze. Slinky Cobalt strings are nickel-free.

Due to the excellent price / performance ratio and the fast delivery, even to Austria, my No.1 when ordering.
The strings themselves exceeded my expectations, because I had not hoped to notice such a difference from regular strings. The powerful warm sound, especially on the low strings, makes them my new favorite strings! Absolutely recommended!
...better!

After years without my JEM77FP, where I changed the strings once a month, I started again a year ago - like before with D'Addario. Then Earnie Balls. Both seemed different to me than before, stiffer and duller. Subjective. These Earnie's sound more metallic - but above all THE PLAYING FEEL IS BETTER, they are softer, not so stiff. From therefore recommendable !
