Independent shopping perspective
The Korena take
Five-string bass set in cobalt alloy, regular Slinky gauge. For players who want a defined low B with more output than nickel-plated steel.
Strong match
Who this is for
- 5-string bass in standard B-E-A-D-G tuning
- Cutting through loud guitars with extra output
- Modern, bright fingerstyle or slap tone
Consider the trade-offs
When to look elsewhere
- 4-string basses — you'd be paying for a spare string
- Players wanting a dark, thumpy vintage voice
- Fretless necks, where roundwounds chew the fingerboard
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
Cobalt alloy
More magnetic response than nickel-plated steel. Helps a low B stay articulate instead of turning to mud.
Detail 03
Regular Slinky gauge
The middle of the Slinky range. Balanced tension — not as loose as a light set, not as stiff as heavy.
Detail 04
Roundwound windings
Textured surface, bright attack, more finger noise. Harder on frets than flatwound alternatives.
Final check
Know before you order
- 01Check your bass is strung through-body or through-bridge — winding length matters
- 02Nut slot may need widening if stepping up B gauge
- 03Setup and intonation shift when changing brands or alloys
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will the low B feel tight?
Regular Slinky sits mid-range in tension. Cobalt's stronger magnetic response helps the B read clearly through a pickup, though string height and scale length matter most.
02Can I use this set on a 4-string?
You could skip the B, but you'd be discarding a string. A dedicated 4-string set costs less and is gauged for it.
03Does cobalt corrode faster?
Cobalt is a different alloy than nickel-plated steel with its own feel and tone. Wipe strings down after playing regardless of alloy — hand sweat is what kills them.
04Do these work on a 35-inch scale bass?
Check the winding length against your bass before ordering. Extended-scale instruments need enough unwound string past the nut to wrap the post.
