Steel core, bright clear sound.

Cons: I had one of these strings given to me to trial before they came on the market and I really liked it. But now somehow they've changed it. Terrible tinny harsh sound, lacking all quality even once played in and has a slow response. Will never buy again! Their G and C strings are much better in quality but would still think twice about using again.
Other: Try Larsen, Evah Pirazzi, Passione or Jargar but not this!
