Comprei 2 jogos de Earnie Ball pra guitarra: --- Cobalto 011 --- Aço inox 009 Por incrível que pareça ambos os jogos de cordas estavam com as 3 mais finas enferrujadas. As cordas são boas. Os lotes da Amazon que não prestam.

These strings sound great and cost good as well. Nothing to complain really. Found them tiny bit tougher than D'Dario Strings(difficult to bend), but that could be a personal observation and might vary.

When I first put these on my Jackson, I was amazed at how bright they were. Then I turned on my amp (Marshall head + 1960 cabinet) and was very disappointed. The strings were TOO bright. I know, that sounds odd, but I just didn't like it. Keep in mind, I'm a "metal" guy, so I like my sound a lot darker, but I always love the bright-yet-evil tones new strings always bring. The Jackson is tuned normally, and I do play more than just metal, but even clean tones and non-metal distorted tones were just too dang bright. The treble nature of these strings + 2x9v EMG-81 bridge pickups kept muddling everything together in a weird, not pleasant way. I've messed with my tone controls a hundred different ways, and no matter what, it was just too bright. I initially was going to give the strings a 1- or 2- star rating, but with the explanation/context of why. They are NOT bad strings at all. Just too freakin' bright and sharp and treble-y. However, I bought these about the same time as I bought my wife an electric bass + amp. I decided to leave the strings on the Jackson as my ESP has the super bottom-end heavy strings and is set up and tuned to D, though I spend a lot of time in drop C. So I kept these Cobalts on the Jackson so she and I wouldn't have tuning issues while teaching her to play. Fast-forward about two months, and my initial dislike for the strings has changed. I'm really liking how they've held their brightness, but it has mellowed out quite a bit after 6-8 weeks of banging around on them. Again, still very bright, but yet now they no longer bleed notes into one another while annoying me to death with the sheer high-pitched treble. However, even though I'm very thorough about cleaning strings and the guitar after every use, they are starting to corrode. I play the ESP about 1.5x more than the Jackson, and the ESP's strings are at least twice as old as the Jackson w/Cobalts, yet the ESP's strings are not showing any signs of rusty-corrosion-whatever it is that happens to metal strings. If you're after a really bright tone, these are the best I've ever heard. I'm very tempted to try the super bottom-end versions on my ESP. But like everything audio, everyone's tastes / preferences will be different. There's probably seven other guitarists who are exactly like me in terms of music style and genre preferences who would throw rocks at my head for saying the Cobalts are too bright because to them, the Cobalts are too muddy or such. I'm mostly disappointed that they don't hold up to sweat/moisture as well as the non-Cobalts on my ESP.
