Description
Swap out your dead set for Ernie Ball’s Cobalt Hybrid Slinky (2722) and hear what a real alloy upgrade sounds like. Cobalt reacts to your pickups’ magnetic field more strongly than traditional nickel or steel strings, which means your amp picks up more of what you’re actually playing — tighter low end, ringing harmonics, and highs that cut through without getting brittle.
This hybrid set pairs lighter plain strings with beefier wound strings, so you get the bend-friendly feel of a slinky top end while keeping low-string punch and tuning stability intact. Cobalt’s smooth, silky surface feel makes vibrato and bends feel almost effortless right out of the pack, and that dynamic range holds up whether you’re playing clean or driving your amp into overdrive.
Gauges in this single pack:
- .009
- .011
- .016
- .026
- .036
- .046
If your current strings sound dull, flat, or lifeless, this is the fastest way to bring your guitar back to life. Keep a spare set in your gig bag — Cobalt strings are exactly the kind of upgrade you’ll want on hand every time you restring.
