Description
You know that magic window right after a fresh install, when bends feel effortless and every note rings true? Ernie Ball built the RPS 9 set to stretch that window out. The secret’s in the plain strings: a patented brass wire winding grips tightly around the lock twist at the ball end, cutting down on the slippage and snapping that usually cuts a set’s life short right where you least expect it.
Under the hood, these are nickel-plated steel wire wrapped around a tin-plated hex-shaped steel core, giving you that classic Slinky snap and warmth players have chased for decades. RPS tech doesn’t change the tone you love, it just makes the strings hold their tuning stability and resist breakage longer than a standard plain string setup, so you’re spending more time playing and less time re-stringing mid-session.
Super Slinky gauges keep things fast and bendy:
- .009
- .011
- .016
- .024w
- .032
- .042
Toss a set (or three) in your gig bag. Whether you’re restringing before a set or just topping up your stash, StringRush keeps these in stock so a dead-string emergency never derails your practice or your show.
