Detail 01
Flatwound construction
The outer wrap is a flat ribbon, not round wire. Smooth under the fingers, almost no squeak, and much gentler on frets.

Independent shopping perspective
Medium-gauge flatwound set for 5-string bass. For players who want thump and a smooth, quiet fretboard rather than modern brightness.

What matters in use
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 01
The outer wrap is a flat ribbon, not round wire. Smooth under the fingers, almost no squeak, and much gentler on frets.
Detail 02
Includes a low B. Check your bass takes a B through the tuner post and bridge without binding.
Detail 03
Middle-ground tension. Flatwounds already pull tighter than roundwounds at the same gauge, so this feels firmer than a medium roundwound.
Detail 04
Fundamental-heavy with rolled-off highs from day one. The sound changes very little over months rather than dying after two weeks.
Detail 05
Flat surface won't gouge an unwound fingerboard, which is why fretless players almost always run flats.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
Far longer than roundwounds. They start dark and stay close to that tone, so many players keep a set on for years rather than months.
Yes. The smooth outer wrap won't dig into the fingerboard the way roundwound windings do, which is the main reason fretless players use flats.
You can, but you won't get the bright metallic pop. Flats give a duller, thuddier slap tone. If slap is your main technique, look at roundwounds.
Yes. The surface is smooth instead of ridged, so your fingers slide without squeak. They also feel stiffer under the left hand at the same gauge.
