Sunbeams are premium, nickel-plated bass strings wound on round cores. Perfect for traditional and fretless players wanting a smoother feel as well as more brightness and warmth. Sunbeams feature the easily recognizable feel and flexibility of DR round-core construction with nickel warmth, softness of feel, and increased response to magnetic pickups due to the sensitive magnetic content (compared to stainless steel) of the nickel-plated wrap wire.
