loved the idea. used it for some pre-recording recordings, and for our actual recording. held up pretty good, didnt change the sound or anything. put it to the real test, which was playing a show. considering i would get a lot more sweaty, hit the strings a lot harder, i figured if it worked here, they would work for anything. 35 minutes set killed the strings. well didnt kill, but the tone is just dull and flat, even after i re apply the string life(which is supposed to give them more life) but it did not. looks like i'm going back to elixir.
