​​​​​​DR Strings Black Beauties Electric 9/42 
 
BLACK BEAUTIES™ colored acoustic guitar strings aren’t just about the sleek and sophisticated look. They feature a phosphor bronze wrap wire on a hex core to maintain brightness and feel. All strings in the set have a jet-black version of DR’s K3™ ultra-hard coating. Players tell us these strings have longer life, more projection, greater clarity, better articulation, and fewer unwanted overtones than uncoated strings. 
​
K3™ Coated applied to the wrap wire is extra hard to maintain string brightness while extending life
The coating eliminates unwanted overtones, helping projection, clarity and articulation
The all-black color creates a modern, aggressive and distinctive look
