Description
If your last set felt dull the second you plugged in, Cobalt is the fix. Ernie Ball built this alloy to grab your pickups harder than traditional nickel or steel, translating into stronger output, wider dynamic range, and a tone that stays articulate whether you’re chugging low end or picking out top-string leads.
- Gauges: .008, .011, .014, .022, .030, .038
- Cobalt alloy wrap for a tighter magnetic bond with your pickups
- Extended dynamic range with punchier lows and sparkling, defined highs
- Smooth, silky feel under the fingers — bends and vibrato come easy
Extra Slinky’s .008 top string is about as low-tension as it gets, so if you love fast bends, aggressive vibrato, or just want your fretting hand to breathe easier during long sets, this gauge set delivers. Pair that low tension with Cobalt’s harmonic clarity and you get a set that feels loose but still snaps back with real presence — not the mushy, dead-sounding output you get from strings that have overstayed their welcome on your neck.
Single pack, so grab a few and keep your rotation fresh. Strings degrade the moment sweat and oxidation start creeping in — don’t let old strings rob you of the tone Cobalt is built to deliver.
