D’addario EJ45

All Pro-Arte treble strings are sorted by a sophisticated computer-controlled laser machine which performs diameter/tension measurements and quality checks, insuring true sounding, precise trebles in every set. Pro-Arte basses are wound using silverplated copper on a multi-filament nylon core for consistent, warm-yet-projecting tone. Gauges: .028 .032 .040 .029 .035 .043
