With Ernie Ball single strings, you can customize your preferred set without relying on the standard sizes of pre-packaged sets.

They are made from a special composite of high-carbon steel, which is then galvanized (coated with tin). Suitable for acoustic and electric guitar.

A patented additional winding of brass wire reinforces the winding (end) of the string at the ball. "Slippage" and breakage of strings have been minimized, right where problems used to occur.

RPS strings endure stress better and hold tuning more reliably than traditional strings.
