I knew what to be expecting with these as they are the same brand I rock on my 6 strings. Being new to 7 strings I thought I better try a brand I know so I can focus on the guitar. These are excellent strings!!! 6 string, 7 string, same quality and performance. These have a very specific tone that can only be described as "full" and "clear". Plus, for the cost, I dont think you can do better. Don't waste your money on Ernie Ball Sacks ;-)
