Detail 01
Heavy gauge
More tension, more volume and low end, but harder to fret and bend. Your hand feels it after an hour.

DR StringsBlack Beauties Heavy Acoustic Guitar Strings
1/3
Independent shopping perspective
The Korena take
Heavy-gauge acoustic strings with a black coating-style finish. For strummers who want volume and don't mind higher tension under the fingers.
Strong match
Who this is for
- Hard strumming where lighter strings lose body and go thin
- Players who want a visual contrast against a light-top acoustic
- Drop and open tunings that need tension to stay tight
Consider the trade-offs
When to look elsewhere
- Beginners still building calluses and fretting-hand strength
- Fingerstyle players who want responsive light-touch dynamics
- Vintage or small-body guitars not braced for heavy tension
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Black finish
Coated look that hides fingerprints and grime. Some coating usually wears off at the fret contact points over time.
Detail 03
Acoustic set
Built for acoustic guitars only. The wound strings need a magnetic core to work with electric pickups, and these won't.
Detail 04
Six-string set
Standard six strings, no extras. Doesn't cover 12-string or baritone instruments.
Final check
Know before you order
- 01Heavy gauge usually needs a truss rod adjustment and possible saddle work
- 02Confirm your guitar's builder allows heavy gauge — some smaller bodies do not
- 03Black coating flakes at contact points; that's normal wear, not a defect
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will heavy gauge damage my acoustic?
It raises neck tension. Most modern dreadnoughts handle it, but check with the builder on smaller-bodied, vintage, or lightly braced guitars before switching up from light.
02Does the black coating come off?
Expect wear where your fingers and the frets contact the string. That's cosmetic and doesn't change the tone.
03Can I use these on an electric guitar?
No. Acoustic strings use bronze-family wound strings that a magnetic pickup barely reads. Use electric strings for an electric.
04Will these work with a pickup-equipped acoustic?
Yes with an under-saddle or soundhole system designed for acoustics. A magnetic soundhole pickup is the exception — it needs steel-core wound strings.
