## Description

Product Description Black Beauties bass guitar strings with K3 Technology. The K3 coating is the first coating that players report, "sound as good or better than uncoated strings." DR's remarkable and proprietary K3 Technology coating is the first coating that makes no apologies and no excuses for not delivering sound equal to uncoated strings. Players tell us that these strings have more volume, less unwanted overtones, greater clarity and articulation than standard, uncoated strings. Yet, they provide the same protection due to corrosion and perspiration as well as increased tone life that coated strings are known for. From the Manufacturer BLACK BEAUTIES™ Black Colored Bass Strings aren’t just about the sleek and sophisticated look. They feature a round core wire and a stainless-steel wrap wire to maintain brightness and feel. All strings in the set are coated with a jet-black version of DR’s K3™ ultra-hard coating, delivering longevity, more projection, fewer unwanted overtones, and outstanding clarity and articulation.

## Questions & Answers

**Q: Is the coating smooth to enable glissando on a fretless bass?**
A: Killer on a fretless.

**Q: Are these for short or long scale bass guitar ?**
A: Long scale.  Do a search for short scale strings.

**Q: Does the coating dampen the effects of pinch harmonics? I use harmonics a lot and don't want to lessen that ability.**
A: Not at all.  The coating is sorta like when aluminum is anodized.  Not like other strings with actual coatings on them.  I used them on my Roscoe 5 for several years and now on my Spector NS2 for the last 5 years.  DR makes the best strings.  The feel of these is very similar to the Sunbeams.

**Q: Have you actually ever played a guitar?  How can you sell such a nasty product?  How can you sleep at night?**
A: I play the bass, I've tried a different set of DR coated strings. They're not my thing, but other players want the benefits that coating provides them. Different strokes Kirin. Check out some of the non-coated strings I do carry. Thanks.
