D'Addario ENR71 Half Round Bass Guitar Strings, Regular Light, 45-100, Long Scal...

Coined the “third type of string,” XL Half Rounds bass strings are an excellent medium between round wound and flat wound strings. Half Rounds have a smoother feel than round wound strings, but a fuller tone than strings that are flat wound. Made with a high carbon steel core and pure nickel wrap wire, they’re finished with a precision grinding process to provide a smooth feel and reduced finger noise, with tone that's comparable to round wound bass strings. 45-100 Regular Light is our most popular bass gauge, providing a perfect blend of response and playability.
