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
Flat ribbon outer wrap instead of round wire. Slick under the fingers, almost no squeak, thumpier and darker than roundwound.
Detail 02
Brighter and harder than nickel, and more corrosion-resistant. Holds its top end longer than nickel flats.
Detail 03
Lower tension than standard flats, which normally pull tight. Easier on the fretting hand and gentler on the neck.
Detail 04
Sized for 34" scale basses, which covers most Precision, Jazz and similar four-strings.
Detail 05
The smooth surface grinds frets far less than roundwound. One reason flats last for years, not weeks.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, if it's a standard 34" scale four-string, which almost all Precision basses are. Check your bridge routing if the strings pass through the body.
Far longer than roundwound. Many players keep a set on for years, since flats mellow rather than go dead and the smooth wrap resists grime buildup.
No. Slap wants the bright, aggressive attack of roundwound. Flats sound muted and thumpy under a thumb pop.
Usually yes, since flats run at higher tension. Medium light is the lower-tension option in the flatwound world, so this set feels closer to standard roundwound.
