Review: Great for a begginers, Slinky easy to bend, plus brighten up a cheap muddy sounding guitar too! - Writing a review as I have 13 guitars here in my camper and 6 or so back home. So I am a bit impressed. My situation- I got these thinking the extra magnet and extra slinky attributes would help out my Harley (Fender Sonic Mustang wanna be) as it is a 24 scale and my wife already has the later one and this was cheaper - for basically if and when I take lessons because of the shorter scale length b/c the teacher can put me thru some runs, hammer ons with my pinky etc... You know Harley Benton has a tendency to sound muddy, so thought the extra magnetic drive wouldnt hurt. So... The strings as I was installing them stuck to the pickups b/c the magnetic pull was that strong, and are very slinky AND a bit beefyer fatter to the touch and I liked that too! Sound very good! Most likely from the magnetic quality.
Review: Sound amazing and feel amazing - I was very scheptical of what these would sound like compared to the hybrid set on my Ibanez, I have A Dimarzio Super Distortion at the neck and a Dimarzio Pro Track in the middle and a Dimarzio x2n at the bridge and the hybrid set sounded good but did have that extra part that was missing in the articulation of heavy riffs and stuff and some of the low end was more muddy sounding and seemed to feel a little off when you set the action and so forth, so i tried out these extra slinky and these blow my mind, its like it still does that low end but it has that extra articulation now with that low notes you get, its insane, and alot easier to pull of pinch harmonics and riffs, ultra smooth fret slides, i am super picky on the guitar, i have my frets polished at 12000 mirror like finish and these just glide so smooth on the frets. If you are ultra scheptical about what strings to get and see so many out there and I am glad i found these as these seem more than good enough for me, now it makes me too addicted to Improv playing again with drum beat in background then playing pc games and stuff :)

Ernie Ball Cobalt SS strings. What is not to like. These were the genuine article which is important since there are knockoffs being sold in identical packaging.
