D'addario XTB45130 Electric Bass 5-String Set NPS Long Scale 45-130 - 5-string set

D'ADDARIO XTB45135 5-String Electric Bass Nickel Plated Steel Long Scale Regular Light 045-130 nickel-plated steel 5-string round thread waterproof string set, long scale.
Introduced at Summer Namm 2019, D'Addario XT water-repellent strings (for electric guitars and basses, classical guitars, folk guitars, banjos and mandolins) combine various innovations developed by the American firm to guarantee enhanced robustness, optimal tuning, and extended longevity.
Each string has a high-carbon core, and threads made from the most popular alloys coated with a microscopic anti-oxidant treatment that fully preserves the sound and feel of a traditional, untreated set of strings. They have even been acclaimed by jazz virtuoso Pat Metheny, who found them particularly clear and homogeneous.
