Independent shopping perspective
The Korena take
Standard-gauge nickel wound roundwound bass strings, 45-100. A bright, common-sense replacement set for a four-string electric bass.
Strong match
Who this is for
- Restringing a four-string bass with standard scale tuning
- Players who want defined attack and finger noise under the note
- Slap and pick playing that needs top-end bite
Consider the trade-offs
When to look elsewhere
- Fretless basses, where roundwounds chew up the fingerboard
- Players chasing thumpy, muted vintage tone — look at flatwounds
- Five-string basses or anything needing a low B
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
Roundwound
Ridged outer wrap. Bright and articulate, but you'll hear finger squeak and it wears frets faster.
Detail 03
Nickel wound
Nickel over steel is smoother under the hand and less harsh than pure stainless, with a bit less top-end grind.
Detail 04
Four strings per set
Covers E-A-D-G. A five-string needs a separate set with a low B included.
Detail 05
Long scale
Built for standard 34-inch scale basses. Short-scale instruments need shorter strings to avoid winding over the nut.
Final check
Know before you order
- 01Check your bass is standard long scale before ordering, and measure if unsure
- 02Dropping from 45-105 to 45-100 may need a small truss rod and intonation adjustment
- 03No winder, cutters, or tools included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my bass?
They fit standard 34-inch long-scale four-string basses. Short-scale and extra-long-scale instruments need different lengths.
02Are these good for a fretless bass?
No. Roundwounds gouge unlacquered fretless boards. Use flatwounds or tapewounds instead.
03How does 45-100 compare to 45-105?
The low E is slightly thinner, so there's less tension and a marginally looser feel. Everything else is the same.
04Nickel or stainless steel?
Nickel is warmer and smoother to the touch. Stainless steel is brighter and more abrasive on frets and fingertips.
