Ernie Ball Hyper Slinky Bass (.040–.100) review: exactly between Extra and Super Slinky

Ernie Ball's Hyper Slinky Bass is the newest of seven gauges in the company's 4-string nickel Slinky bass family: .040, .060, .080, .100, wound with nickel-plated steel over a hex steel core. Ernie Ball's own product page describes exactly what it's for: it "sit[s] neatly between Super Slinky and Extra Slinky bass strings for a balanced feel across all 4 strings," built for players who want "moderate tension on the lower strings and lighter tension on the higher strings for added playability and snap." Source: Ernie Ball's own Hyper Slinky Bass product page.

That "sits between" line undersells how literal the fit actually is. Hyper Slinky isn't a blended average of its two neighbors, it's a direct splice: the G and D strings are lifted straight from Extra Slinky, and the A and E strings are lifted straight from Super Slinky. See the exact breakdown below.

Hyper Slinky Bass also isn't an old standby quietly filling a gap. Ernie Ball launched it on April 5, 2022, in the same press release that introduced four new electric guitar Slinky gauges, Zippy, Hyper, Magnum, and Skinny Top Heavy Bottom 7-String.

One naming collision worth flagging before you buy: Ernie Ball's electric guitar line also ships a "Hyper Slinky," a completely different 6-string set gauged .008-.042. Bass Gear Magazine's April 2022 launch announcement lists both in the same breath, "Hyper Slinky (8, 11, 14, 24w, 32, 42)" for electric guitar and "Hyper Slinky Bass (40, 60, 80, 100)" as a separate line item, released the same week under the same family name.

The two strings share nothing but a release date and a name. If you're shopping by search or by memory rather than by package photo, double-check the listing says "Bass" before you add it to your cart, a guitar player's Hyper Slinky on a bass, or vice versa, isn't just the wrong gauge, it's the wrong instrument's strings entirely.

Ernie Ball ships seven gauges under its nickel Slinky 4-string bass line, all confirmed live on Ernie Ball's own catalog page:

• Super Slinky: .045, .065, .080, .100 (P02834). Full review.
• Hybrid Slinky: .045, .065, .085, .105 (P02833). Full review.
• Regular Slinky: .050, .070, .085, .105 (P02832), Ernie Ball's standard-tuning default. Full review.

• Beefy Slinky: .065, .080, .100, .130 (P02840), the heaviest. Full review.

The exact fit between the three lightest sets is worth seeing string by string, not just described:

Hyper Slinky's G and D strings are identical to Extra Slinky's, unchanged down to the thousandth of an inch. Its A and E strings are identical to Super Slinky's. That's not a coincidence of rounding, Ernie Ball built Hyper Slinky as the exact midpoint set for players who want Extra Slinky's easy top-string feel without giving up Super Slinky's low-string body.

Ernie Ball Hyper Slinky Bass has a real, if modest, track record on bass forums going back to its 2022 launch. One player on TalkBass bought a set the week it appeared in stores and reported back after stringing up a Sterling: "sounds good for what they are but they feel taut compared to the Super Slinky set. May need to stretch them out some more for a week and see what they're like." Source: TalkBass.com, "New Ernie ball hyper slinky!," April 2022. That's a useful, honest data point: expect a stiffer break-in period than the lighter Extra Slinky, even though the top two strings are the same gauge.

A 2024 TalkBass thread shows the set doing real work as a beginner recommendation. A new bassist coming off .045-.105 factory strings on an Ibanez, wanting something easier to fret for root-note hard rock (Kiss, Motley Crue-style playing), asked whether to go with Hyper Slinky or Extra Slinky. An experienced member's answer was direct: "If you've been playing 45-65-85-105 and want to go lighter, 40-60-80-100 would be the most logical choice." A second reply suggested Super Slinky as a further option, noting that root-note rock rarely touches the D and G strings anyway, so the E and A gauge matters most.

• Players stepping down from Regular Slinky or Hybrid Slinky Bass who want a real gauge reduction without jumping all the way to Extra Slinky's lightest spread.
• A lighter fretting hand on the G and D strings while keeping more low-end body on the A and E than Extra Slinky offers.
• Root-note rock and hard rock playing (the style the 2024 TalkBass thread specifically discusses) where the E and A strings carry most of the workload.
• Players who found Super Slinky slightly stiff up top and want the same low-string feel with an easier-fretting G and D.

• Players who want the lightest possible tension across all four strings. Extra Slinky is lighter on the bottom two strings; go there instead.
• Drop tunings played stock. A .100 low E is standard-tuning territory. Look at Regular Slinky, Power Slinky, or a 5-string set for anything lower.
• Anyone expecting a broken-in feel out of the pack. The one detailed first-hand report available describes the set as noticeably taut fresh out of the package, plan on a real stretch-and-settle period.
• Players chasing a long endorsement history. Hyper Slinky is a 2022 addition to the line with no significant artist wiring documented yet, unlike Regular Slinky or Super Slinky's decades on stage.

Standard nickel roundwound install: bring the set up to pitch, stretch each string gently along its length a few times, retune, and repeat two or three times before trusting it live or in a session. Budget more break-in time than usual here. The only detailed first-use report available describes the set as feeling "taut" straight out of the pack compared to Super Slinky, so give it the full stretch-and-settle cycle, and don't judge the final tone or feel until it's had at least a full practice session under tension.

Hyper Slinky Bass earns its place with simple arithmetic: it's Extra Slinky's G and D strings paired with Super Slinky's A and E strings, not a rough approximation but an exact match at every gauge. If you've outgrown a heavier factory set and want an easier fretting hand without losing low-end body, or if you liked Super Slinky's bottom end but wanted a lighter top, this is the specific set built for that gap.

The tradeoffs are honest ones. It's a young addition to the Slinky family with no deep artist pedigree yet, and the one detailed real-world report on hand says it needs a real break-in period before it settles in. Neither is disqualifying, but go in knowing both.
