600 Series -- Black Diamond Acoustic Guitar

If a crisp, brilliant sound is what you want, then the special phosphor bronze round wound strings are the answer.  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 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.
