Black Diamond 500L Nickel Round Wound light

Natural Uncoated is exactly that. Our original and natural Black Diamond strings. The core is the pulse of our string. It’s the heartbeat. We pull our high-carbon steel core to the optimum playing tension on our custom-made machines before winding the NPS8 Nickel wrap at 8,000 rpm with 35% braking tension while at a -1 pitch. This produces a string that opens up smoother while still retaining great sustain and volume. Since 1890
