Luca Monforte: I didn't get these looking for increased output or anything like that. On tour this summer I started having issues with my fingers, between heat, road conditions and a ton of hand sanitizer but finger tips kept getting this weird rash. On a break I basically only played my nylon and it immediately went away. I think for some reason the conditions caused me to be sensitive to nickel. I switched to these and it hasn't been back since. They're brighter than nickel at first, it kind of reminds me of the tone metal bass players get by always using new strings. But we just tweaked my high mid gain and it sounded normal. I'm going to switch back to my regular strings now that I'm home but I'll keep some sets of these around in case.

Not Shane Lol: Read the title. Was tuning my friend's majesty and he was still rocking the stock strings from a few months ago. Slapped on these bad boys, I couldn't stop playing it sounded so good. Layed down some nasty deathcore covers and can confidently say these will definitely deliver on any of your 7-string needs. Crisp cleans? Too easy. Insane shreds. Not a problem. Weird ass alien noises? Sure, why not?

Nikolas Bridges: If you like low tunings for a 7 string then these are for you! These strings are amazing! They sound great for jamming metal! My dad has been playing the guitar since he was a kid and he says these are the best strings he has ever played with! Definitely gonna be buying more!

in Poche parole: se sei un old school che usa ancora la sette corde come me e non è passato alla otto corde come i nuovi tamarri della chitarra fermati e leggi qui. Ero un po' scettico per questo prodotto cobalt, sia per il prezzo sia per le recensioni mirabolanti. pero provandole e registrando il suono è realmente piu cristallino, ottime per il suono djent di Meshuggah e simili, molto dleng dleng. Mi sembrano anche piu resistenti. Prodotto promosso

Patrick: All comparisons/descriptions are in the context of my guitar (alder body, maple/pau ferro neck with SS frets, hard-tail bridge). I've been using Stringjoy strings for a while now (freaking fantastic by the way, as customizable as you could want gauge-wise) which are very full and lively (lots of harmonics, plenty of mids and they feel amazing for strings made of standard materials). The Cobalts, by direct comparison, have a lot less mids, around the same amount of low end and a bit more presence on top. They jangle very well and would be great for a guitar/pickups that are a little clogged up in the midrange. The set I normally use has gauges very close to this set of cobalts, but the cobalts feel a bit more loose than I would have expected (a few reviews I read stated that, when questioned, the folks at EB said that they're made with a slightly smaller core wire and that's fairly easy to see when inspecting the ball end during installation). They feel a bit rougher than what I'm used to, but they aren't uncomfortable by any means. I feel the greatest strength of this material is just how controlled/quiet they sound. Not just because of the slight scoop in the mids, but I don't...
