D'Addario Classical Hard Tension, Silverplated Wound, Black Treble EJ50 Strings

EJ50 hard tension classical strings featuring custom extruded black nylon trebles are a popular choice for their rich tone, increased resistance, and strong projection. All Pro-Arté treble strings are computer controlled by an X-Y laser microscope which performs diameter and tension measurements, ensuring true-sounding, precise trebles in every set. Pro-Arté basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone.
