D'Addario's ENR72 Half Rounds sit between the brightness of roundwound strings and the muted thump of flatwounds, offering bass players a middle ground that's often overlooked. The nickel–wound construction is ground down after winding, creating a semi–flat surface that reduces finger noise and fret wear while retaining more harmonic content than traditional flatwounds. This Medium gauge set spans 50–105, delivering balanced tension across a long–scale bass without the stiffness that can make heavier flatwound sets feel like steel cables.
Each string uses a hex–shaped steel core wrapped with nickel–plated steel, then precision–ground to remove the outer ridges of the winding. The result is a smooth playing surface that glides under the fingers but preserves the magnetic properties needed for clear pickup response. Gauges run .050, .070, .085, and .105 inches, providing enough mass for drop tunings while keeping intonation stable across the fretboard. The long–scale length accommodates 34–inch basses and works with most through–body or top–load bridge designs without excess string beyond the tuning post.
