The strings of the electric bass have a larger diameter than the electric guitar, since the higher the string mass changes the vibration behavior in such a way that the desired deep tone can only be achieved with an acceptable string tension with thicker strings. Roundwound strings are wrapped with a round wire, while flatwound strings are wrapped around the core with a flat metal tape, which makes them feel a little softer. In terms of sound, flatwound strings generate little or no noise when you slide your fingers over the electric bass strings. But they don't sound as bright as roundwound strings. Due to the lower friction, such strings are initially more comfortable on the fingers.
