Description
Known for their distinctive “ultra black” colour, Ultra Blacks work well for the player seeking a fuller, darker-sounding string for traditional jazz and other styles. They have a darker tone, akin to gut strings, but with more snap and definition in pizz. The Ultra Blacks also respond easily under a bow.
Ultra Blacks fill the void between the traditional gut string sound and more modern steel strings. They have a solid fundamental with good sustain, suitable for nearly all pizzicato work, be it jazz, bluegrass, folk or traditional.
