Bright notes on all strings with a ton of overtones and harmonics and these strings do increase the output signal from the pickups, had to turn the volume down on several guitars that previously had weak outputs. Will purchase more for my other guitars.

Great practice for aspiring metal players. The strings are thick, hard to work with and hurt, but thats what makes it great, its good for aquiring the discipline needed for guitar early on. When you finally drop to standard string gauges you will feel like your playing with spaghetti and tones will be more clear, overall playing will be easier. The perfect bootcamp strings in my opinion.

These are the only electric guitar strings I buy. I'm just glad I do not have to drive all the way to Guitar Center now. Thanks, Amazon!

I've been playing a mixture of Acoustic and Electric Guitar for about 6 years now. I used to use super slinky strings and loved them, but I wanted something different to see what else was there. I found these, and after some research on them, I was interested and purchased them. I love them. They are my new go-to strings now, and they are worth the money you spend on them. They give excellent tone, perfect for any genre of music.

Been playing about 4 years, used all sorts of strings from Elixir coated to EB standards and other premium strings. Coated were my favorite originally until I realised the coat actually does more damage than good as the strings begin to age. I was kind of lost till I ordered these. The only patented cobalt strings so you can't get these under any other brand name. The material genuinely does make a difference in terms of sound and response from the pickups. Playing feels easier, the strings feel a lot nicer, probably more so than any coated strings I have tried, great for slides/bends. They hold their tuning great after very little stretching and they seem to be a lot tougher than usual strings despite seeing the odd review claiming to have snapped the e string but I'm more inclined to believe that is down to being too eager when tuning. Overall amazing strings and worth every penny just for the sound and the playability aspect. I'll never be going back to non cobalt guitar strings after the experience.

They are actually really great strings. I really didn't notice much difference "tonewise" compared to the regular Super Slinky Ernie Ball strings that I use. I just thought I'd give them a go. Maybe they are a little more slick and bend a little smoother?? That may have been a placebo effect to justify paying the extra for these strings though haha... Overall I'll just go back to the Super Slinkys. Ernie ball are the only strings I'll use though.
