This wound E string sounds as an extension of the other strings, not as a completely separate entity as many E strings do.
If you want a piercing and clear sound out of your E string, this string is not for you.
If you want a mellow and warmer sound that is more in line with the other strings, you won't be able to find any better than this one.
I have used it on an electric violin so the sound would not be so thin, and the string performed that task perfectly. Highly recommended.
