Ernie Ball Paradigm Ultra Slinky (.010–.048): Regular Slinky's top strings, Power Slinky's low end
Reviewed by the Change Your Strings editorial team ·
Ernie Ball Paradigm Ultra Slinky (P02017) is a hybrid gauge: Regular Slinky's .010, .013, .017 top strings paired with Power Slinky's .028, .038, .048 low strings. Paradigm construction adds Everlast nano-treatment, plasma-enhanced wrap wire, and RPS ball-end reinforcement, with lab-tested claims of up to 35% more tensile strength and 70% more fatigue strength, backed by a 90-day breakage and rust guarantee. Suits E-standard players who want extra low-end weight without a stiffer top.
What this set is
Ernie Ball Paradigm Ultra Slinky is a hybrid gauge built from two of the brand's oldest and most familiar sets. The top three strings, .010, .013, .017, are Regular Slinky's exact plain strings. The bottom three, .028, .038, .048, are Power Slinky's exact wound strings. Put them together and the result is .010-.048: more low-end weight and pick resistance than Regular Slinky gives, without the stiffer bends and bar chords that come with a full Power Slinky .011 top.
Paradigm layers three durability upgrades on top of that gauge, the same construction used across the whole Paradigm line:
- Everlast nano-treatment on the wrap wire surface, applied after winding, corrosion resistance without the full-coating feel of a polymer-coated string
- Plasma-enhanced wrap wire for tighter wind tolerance and a longer brightness window
- RPS (Reinforced Plain String) ball-end technology plus a re-engineered ultra-high-strength steel core in both the plain and wound strings
Ernie Ball backs the construction with a 90-day breakage and rust replacement guarantee and lab-tested claims of up to 35% more tensile strength and up to 70% more fatigue strength than traditional strings. Players who like the idea of Ultra Slinky's in-between gauge but tour or gig hard get the same feel with fewer mid-set string changes.

A gauge built by combining two others
Ultra Slinky isn't a signature request or a decades-old legacy gauge. It's one of two hybrid sets Ernie Ball introduced together in March 2019, described at the time as the company's first new gauge strings in more than a decade. Burly Slinky launched the same way alongside it, combining Power Slinky's top strings with Skinny Top Heavy Bottom's low end. Ernie Ball built both by mixing and matching wound and plain strings from sets it already sold, rather than engineering a new gauge layout from scratch.
That approach makes Ultra Slinky predictable if you already know the two sets it's built from. If you've played Regular Slinky, the fretting-hand feel on the first three strings doesn't change. If you've played Power Slinky, the low E under your picking hand feels the same. The only unfamiliar part is how those two feels sit together on one neck, and in our experience that's a short adjustment rather than a full relearn.
Paradigm construction doesn't change that voicing story. The plasma-enhanced wrap and Everlast nano-treatment extend string life and delay corrosion; they don't retune the tonal character the way a wrap-alloy swap (Cobalt) or a core-alloy swap (M-Steel) would. Broken in, a Paradigm Ultra Slinky sounds close to a standard nickel Ultra Slinky, just built to hold that tone longer.
Where Ultra Slinky sits in the Paradigm lineup
Four Paradigm gauges cover the space between a stock E-standard set and a full step-up gauge. Ultra Slinky sits between Regular Slinky and Power Slinky, sharing a string with each on either side:
| Ultra Slinky (this set) | Regular Slinky | Power Slinky | Skinny Top Heavy Bottom | |
|---|---|---|---|---|
| Gauge | .010–.048 | .010–.046 | .011–.048 | .010–.052 |
| High E / B / G | .010 / .013 / .017 | .010 / .013 / .017 | .011 / .014 / .018 | .010 / .013 / .017 |
| D / A / Low E | .028 / .038 / .048 | .026 / .036 / .046 | .028 / .038 / .048 | .030 / .042 / .052 |
| SKU | P02017 | P02021 | P02020 | P02015 |
| Best known for | Power Slinky low end, Regular Slinky top | The default E-standard gauge | The classic Eb-standard / Drop D step-up | Heavy rhythm strings, light lead strings |
Reading the table by wound strings: Ultra Slinky and Power Slinky share an identical D, A, and low E, so the picking-hand resistance on rhythm parts feels the same on both. Reading it by plain strings: Ultra Slinky and Regular Slinky share an identical top three, so bends and lead lines feel the same on both. Skinny Top Heavy Bottom goes a step further in the same direction Ultra Slinky points, keeping Regular Slinky's light top but pairing it with an even heavier .052 low string built for Drop D.
If you're not sure Ultra Slinky is the right amount of change, Paradigm Regular Slinky is the safer default and Paradigm Power Slinky is the bigger step. See how all five Ernie Ball electric lines compare in our Ernie Ball string lines compared guide.
Best for
- E-standard players who pick hard. The heavier D, A, and low E hold up to aggressive rhythm attack better than Regular Slinky's lighter wound strings, without changing how bends and leads feel.
- Eb-standard players who find a full Power Slinky top stiff. Ultra Slinky keeps Regular Slinky's lighter .010 top three strings while adding some of the low-end weight Eb standard wants.
- Touring and gigging guitarists who want fewer mid-set string changes than an uncoated set gives, backed by Ernie Ball's 90-day guarantee.
Worst for
- Players who want a straight, uniform step up: a full Paradigm Power Slinky gauge changes all six strings together instead of just three
- Dedicated Drop D or lower: the .010 top wasn't built around a dropped low string; Skinny Top Heavy Bottom Paradigm or a full Power Slinky set are better matched
- Budget-conscious daily players: a standard nickel Ultra Slinky (2227) at a lower price tier performs well for casual, low-mileage use without the Paradigm construction premium
Verdict
Ultra Slinky Paradigm is a narrow, specific fix: Regular Slinky with more low-end weight, or Power Slinky with an easier top three strings to bend. It isn't trying to be a dramatic departure from either set, it's built from pieces of both. Reach for it if Regular Slinky's low strings feel thin under a hard-picking hand, or if Power Slinky's .011 top always felt heavier than your lead playing wanted.
The Paradigm construction doesn't change that calculus, it just extends how long the feel lasts. If you already know you want this gauge in standard nickel or Cobalt, compare all three builds in the FAQ below before buying.
