Ernie Ball RPS Reinforced Plain Steel 10 (.010″) Single Guitar String
Ernie Ball Plain Steel Custom Gauge single strings for electric or acoustic guitar. Made of specially tempered tin plated high carbon steel. A patented winding of brass wire is tightly wrapped around the lock twist of the ball end. String slippage and breakage are minimised at the ball end where these most often occur. RPS strings last longer and stay in tune better than conventional plain strings.
