More output than other strings, smooth and velvet-like feel, brighter and bigger dynamic range - these are just some of the terms being applied to Ernie Ball's new Cobalt electric guitar strings.
Cobalt has a stronger magnetic appeal for pickups, making them louder than other alloys on the market. They also sound brighter, as if your amp's EQ has changed a little - low notes seem more defined, mids are tighter and a little 'dust' has been removed from the treble frequencies.
Even with just acoustic playing (not plugged in), the guitar is impressively alive. In short, what you play sounds more defined and focused.
The tone isn't the only difference though - string feel is commendable too being almost softer under the fingers but very responsive to fretting hand articulations like bends and pull-offs. With the promise of resisting sweat and moisture, you stand to get more mileage out of a set than standard strings too.
We've tried them for a week, playing every night and they still sound and feel great. With an RRP of £13.95 they're not cheap (and only six string packs are available at present) but the new tone and feel may impress you enough to make the change for good!
