Detail 01
Flatwound construction
Ribbon winding leaves a glassy surface. No finger squeak sliding between positions, and far gentler on frets.

Ernie Ball2804 Flat Wound Group II Electric Bass Strings
Independent shopping perspective
The Korena take
Flatwound bass strings for players who want a smooth, thumpy tone with no finger squeak. A deliberate move away from bright roundwounds.
Strong match
Who this is for
- Motown, reggae and soul players chasing old-school thump
- Fretless bass, where flats save the fingerboard from wear
- Recording where string noise bleeds into the track
Consider the trade-offs
When to look elsewhere
- Slap and pop players who need aggressive top end
- Modern rock and metal tones built on bright grind
- Anyone unwilling to redo setup after switching from rounds
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
Group II gauge
A middle-of-the-road flatwound set — enough tension for definition without the stiffness of the heaviest flats.
Detail 03
Flatwound tone
Rolled-off highs and a strong fundamental. Notes thump rather than ring, and sustain shortens compared to rounds.
Detail 04
Higher tension than roundwounds
Stiffer under the fingers. Bending is harder and you may need to adjust the truss rod after fitting.
Detail 05
Long service life
Flats do not lose brightness the way rounds do, because they had less to begin with. Sets last years.
Final check
Know before you order
- 01Expect a truss rod and intonation check after switching from roundwounds
- 02Confirm your bass scale length before ordering — long scale is not universal
- 03Flats sound dull at first and open up over weeks
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my bass?
Check your scale length and whether your bridge is top-load or string-through. String-through routing needs extra length behind the ball end.
02Why are flatwounds more expensive than roundwounds?
The flat ribbon winding is harder to manufacture. They also last far longer, so cost per year of playing is usually lower.
03Do flatwounds work for slap?
You can slap them, but the pop lacks the bright snap flats are designed to remove. Most slap players stay with roundwounds.
04Are these good for fretless?
Yes. Flatwounds are the standard fretless choice because the smooth surface does not chew up an unwound fingerboard.
