La Bella L-7716LC double bass string C-5, black nylon tape wound, rope core, extended scaleLa Bella L 7716LC double bass string C 5, black nylon tape wound, rope core, extended scale Over 20 years ago, LaBella worked together with both Attila Zoller and Ron Carter on this string construction. Obtaining the tone of gut and the sustain of metal, this string design is great for jazz pizzicato solos. The rope gut core with the black nylon tape outer wrapping provides a bright attack with a warm tone.
