Nylon tape wrap
The outer layer is nylon, not metal. Softer under the fingers, darker tone, and far less fret wear.

Independent shopping perspective

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 layer is nylon, not metal. Softer under the fingers, darker tone, and far less fret wear.
Detail 02
Smooth surface instead of ridged windings. No squeak when you shift, and much less finger noise through an amp.
Detail 03
Cosmetic, but it reads clearly against a light fingerboard and looks intentional on a fretless.
Detail 04
Scaled for bass, not guitar. Check your string-through or top-load routing before ordering.
Detail 05
Rotosound's darkest, thumpiest set. This is the tone extreme, not a middle-ground flatwound.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, and they are a common choice for it. The nylon wrap is gentler on an unlined or uncoated fingerboard than roundwound steel.
Yes. Nylon tape is darker and thumpier than metal flatwounds, with a shorter, more muted decay. The black coating itself is cosmetic.
The nylon wrap will show wear where you pick and where you fret over time. That is the wrap itself, not paint sitting on top of it.
Only if the set's length covers your scale. Check the winding length against your bass before ordering rather than assuming.
