<p><span id="productDescription" class="cms-copy">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.</span><br /><span id="subBrandDescription" class="cms-copy sub-brand-description"><span class="screen-sm-hidden"><br /></span>D'Addario Half Rounds bass strings are round wound with pure nickel, then precision ground, leaving the outer surface smooth and semi-flat. The result is a string with the tone and tension of round wound strings, plus a smoother feel, like that of flat wound.</span></p>
