Many call this gauging the "Jimi Hendrix" set. These strings are as "vintage" as you can get. Pure nickel wrap on a round tin-plated, high carbon steel core. Many players believe that round core strings have a feel easier to play with less tension and have a clearer tone. By design, round core strings must be handle carefully so that the outer winding does not come lose. On guitars that have a an eye in the tuning post, it is important to install the string and tune to pitch before cutting the excess string off. On guitars where the tuning post has a hole down the center which require the string to be cut prior to placing the string down the post hole, it is important that to you first make a 90 degree bend before cutting the string. It best to make that 90 degree bend about two inches longer than the post where you will be installing the string. Once you have made the bend leave about one-half inch before cutting the string then place the bent section inside the tuning post and tune to pitch. Be aware that it takes longer for a round core strings to "settle" in and it requires many more tugs, but once installed and settled in, they are amazing.
I have been chasing the sound I want for about ten years since i started playing and have finally found the perfect set of strings for that 60's sound. I was always curious about how Peter Green, early Clapton and all these British blues players got such wide, even vibrato and its because of how light, yet well balanced these are. If you are a serious blues rock player, these are the strings that will let you finally find your own voice or help emulate your hero's. I honestly have never been more satisfied with a product!
