Ernie Ball Super Slinky RPS Nickel Wound Electric Guitar Strings - 9-42

Ernie Ball Super Slinky RPS Nickel Wound Electric Guitar Strings in 9-42 gauge are designed for players seeking classic light string tension with added reinforcement at key stress points. Slinky strings have a long history of use by notable artists like Eric Clapton, Jimmy Page, Slash, and Metallica.

The standout feature of the RPS series is the patented brass wire winding. This extra wrap is applied tightly around the lock twist near the ball-end of the plain E, B, and G strings. By reinforcing this specific area, the design directly minimizes common ball-end slippage and string breakage during play.

For the wound strings (D, A, and low E), Ernie Ball uses nickel-plated steel wire wrapped around a tin-plated, hex-shaped steel core wire. This standard construction paired with the California-based manufacturing process ensures consistent build standards across the entire set.

Because the extra brass wrap is focused exclusively on the plain strings, players looking for reinforced windings across the wound strings will not find them here. The set is also strictly configured in the light 9-42 sizing, which may not suit guitarists who prefer heavier tension sets.

Verdict: Ernie Ball Super Slinky RPS strings are an excellent choice for electric guitarists who prefer a 9-42 gauge and want extra ball-end security on their plain strings. They provide dependable, USA-made construction for everyday playing.

A great fit if you:

• Play electric guitar and prefer light 9-42 gauge strings
• Experience string breakage or slippage near the ball-end on your plain strings
• Prefer guitar strings manufactured in the USA

Consider something else if you:

• Prefer heavier string gauges than 9-42
• Do not need reinforced brass windings at the ball-ends
