D'Addario Zyex 3/4 Contrabass String Set Light Tension Purchased January 2025 Due to my lack of knowledge, these strings didn't fit my EUB, so I'm selling them. The A, D, and G strings are unopened and unused. 【Important Notes】 The E string has been cut (see photo). The remaining length of the cut string is 135mm, with 5mm fraying. The E string was installed once and then immediately removed, but because it has been cut, it cannot be used normally. Please consider it as an accessory. Please agree to the above before purchasing.
