GHS R+EJM (11-52) ERIC JOHNSON A high quality core wire is wrapped with a round, pure nickel cover that is slightly flattened by computer controlled precision rollers in the winding process. The result is a semi-flat string that has a warm but articulate tone, which feels great under the fingers. Eric Johnson uses these two sets depending on his preference of string tension for different guitars or a specific tone in the studio. For the most part the medium weight set would be for the shorter scale guitars and the light set would be for the longer scale guitars.Introducing our brand new NitroPack singles!
