Set 760CB 5-string 060/070/094/115/135. Compared to the regular La Bella White Nylon Tape strings, the Copper White Nylons feature a copper base beneath the transparent nylon layer. This results in a warmer tone and allows for effortless sliding over the string. Notably, they also provide a beautiful long sustain. These strings can be used on electric, acoustic, and fretless basses.
