Independent shopping perspective
D’Addario’s NYXL 45–125 Light Top/Medium Bottom set is made for long-scale 5-string basses. Its hybrid gauge uses slightly thicker A and E strings with a slightly thinner low B than the brand’s Regular Light 5-string set. An NY steel core, Fusion Twist technology, nickel-plated steel wrap wire, and revised core-to-wrap ratio support higher break strength, improved tuning stability, and accentuated harmonics while retaining a familiar feel.
