Flatwound

Flatwound refers to a type of wound string used on some electric guitars and basses, distinguished by a wrap wire that has been flattened into a ribbon rather than round in cross-section. The flattened wrap is wound around a core, producing a very smooth outer surface that reduces friction against the fingerboard and minimizes finger noise when played. Flatwounds are relatively common in jazz-oriented instruments and vintage-style setups, and are still manufactured today by major string makers for players seeking a specific tonal character.

The tone of flatwound strings is typically described as mellow, warm, and smooth, with a softer attack and more even overtones compared with roundwound strings. They tend to produce less brightness and bite, with a more pronounced midrange. The feel is often considered very smooth under the fingers, which many players associate with a vintage or classic jazz aesthetic. Individual results vary with instrument, gauge, and setup.

In practice, flatwounds are available in various gauges and for multiple instrument models. They can require different setup considerations than roundwounds because the tension and playing feel differ. Some players find they settle in more slowly and are less forgiving for aggressive picking or bending, while others value their distinctive, understated character. Overall, flatwounds offer a distinct option for players pursuing a particular sound and playing experience.
