well there strung up, as far as sound quality goes, they definatly sound good, but new strings always do after playing old ones, so i think after about a week i should get a real idea of how they sound. Thing that jumps out at me right away is there slicker.. they kind of feel like they have finger-ease on them, which i like. They also seem to have a slight bit more tension then my usual ernie ball slinkies i use. which i also find to be a plus, i like tense strings. I did a punch in test on a song i was working on yesterday. I punched in at a random spot, then played it back with my eyes closed, and did not noticed my punch in, so as far as added output, the waveform says its just about the same, so if there is added output, it must be microscopic. I FEEL a difference, but oddly enough can not hear a difference on a recording. Also, my guitar seems to be picking up more interference and unwanted noise then usual.. but im not ready to blame the strings for that yet.
Pros: Silky, higher tension, FEEL better even though i cant HEAR a difference
Cons: cost, unwanted noise (maybe? still not sure if its caused by something else), gave me cancer.
Conclusion: If the noise is not caused by the strings.. and they come down in price to a little closer to regular strings, the feel of them alone would be enough for me to switch. If your looking for a revolution in strings, i dont think this is it, but if your looking for a change, and like slicker strings with higher tension, give em a shot. I would love to hear others opinions.
I will update my review of them after i play them for a week or two.
