Ernie Ball .009 RPS Reinforced Plain Electric Guitar String - Single

Patented bronze winding is tightly wrapped around the double-ended string termination.

Ernie Ball Nickel Wound RPS Slinky strings are made from nickel-plated steel wound around a tin-plated hex steel core. The plain strings feature patented winding using bronze wire around the termination loop on the end ball. This minimizes the chance of the string slipping or breaking. RPS strings last longer and hold tuning better than traditional strings.
