Medium 4 extra long-scale string set for electric bass guitar from NANOWEB series with ultra-thin (5-micron) coating that protects the entire string, keeps gunk out of the gaps between the windings, and delivers extended tone life, balanced sound and extra-long lifespan of the strings. Special coating also reduces unnecessary finger friction and squeak, therefore enhances the playability and provides consistent performance. Strings are made with steel core and nickel-plated steel winding, and deliver rich, rounded tone with greater clarity. Gauges: .050, .070, .085, .105.
