Really awesome string, worth every penny! Noticeably lower tension than a normal set of 11's, makes for very easy playing which was what I was mainly looking for. They also added tons of responsiveness at lower volume levels, for some reason these strings really get the guitars top vibrating. Really had to pound on the old strings to get the guitar into the 'sweet zone', now it just sounds sweet at all levels. On top of all that they really do get 'more' out of the guitar. I feel like I can hear more overtones and just a generally more appealing tone to my ears. These were put on a vintage Gibson that I was thinking of selling because I wasn't happy with the tone, now there is no way it's leaving me!
