Detail 01
5-string set
Includes the low B. Buying a 4-string set and adding a single B rarely balances tension across the neck.

1/2
Independent shopping perspective
The Korena take
A five-string bass set from Ernie Ball's Power Slinky line. For players on a 5-string who want a heavier feel than a standard light set.
Strong match
Who this is for
- 5-string basses tuned to low B standard
- Players who dig in hard and want stiffer response
- Restringing on a budget without dropping to no-name sets
Consider the trade-offs
When to look elsewhere
- 4-string basses — you'd pay for a string you can't use
- Players who want a slinky, low-tension feel under the fingers
- Anyone needing a specific gauge outside the Power Slinky spread
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Power Slinky
The heavier end of the Slinky range. More tension, firmer feel, stronger fundamental — at the cost of easy bending.
Detail 03
Bass guitar strings
Sized for standard-scale bass. Won't fit short-scale or extra-long-scale instruments without checking winding length.
Detail 04
$27.99 per set
Roughly what a mainstream 5-string set costs. Price scales with the sixth string's material, not brand markup.

The part number is how you reorder the exact same feel later. Slinky names repeat across gauges.
Final check
Know before you order
- 01Check your bass's scale length before ordering — long-scale sets won't work short-scale
- 02Heavier gauges raise tension; the truss rod may need a small adjustment after
- 03Nothing else included — no winder, no cutters, no cleaning cloth
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my 4-string bass?
You'd use four of the five and waste one. Buy the matching 4-string set instead — the tension balance is designed around the full set.
02Do I need a setup after switching to these?
If you're coming from a lighter set, likely yes. Higher tension pulls more relief into the neck. Check the action and intonation before deciding.
03How is Power Slinky different from regular Slinky?
Heavier. More tension, a firmer feel, and a stronger low end. Bends take more effort and the strings sit tighter under your fingers.
04Can I tune down with these?
The heavier gauge holds up better in drop tunings than a light set. Expect to re-intonate after any tuning change.
