The La Bella 7720M flat wound double bass strings are wound on a traditional rope core, delivering the complex, resonant tone that orchestral and jazz bassists prize. Medium gauge provides solid tension for confident bow work and strong pizzicato response, while the rope core adds a warmth and flexibility that steel cores simply cannot replicate.

Flat wound construction gives these strings a smooth feel and a focused sound with controlled overtones. Under the bow, they speak evenly across all four strings with a rich, singing quality. For pizzicato, expect a round, warm attack with good sustain. The rope core also makes these strings more forgiving on the left hand during long rehearsals and performances. If you're looking for a traditional-sounding double bass string with real depth and character, the 7720M set is a serious contender.
