Ernie Ball .012 RPS Reinforced Plain Electric Guitar Strings Single - 1 pcs

The patented bronze winding is securely wrapped around the double end of the string.

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