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. Made for 6-string basses, this 30-130 Regular Light Long Scale set takes our most popular gauge and adds a low B-string on the bottom, as well as a high C-string on top.
