D'Addario Pro-Arté DynaCore sets are constructed from multifilament stranded core material and feature a revolutionary winding technique. The result is a unique modern sound: powerful, round, and with dramatically increased longevity and tuning stability. The set is completed with titanium trebles for optimal sound balance, as usual laser-measured and selected for consistent quality. Gauge: .0290, .0333, .0416, .030, .036, .047.
