## Description

D'Addario Phosphor Bronze Acoustic Guitar StringsYour strings matter. D'Addario's Phosphor Bronze acoustic guitar strings are engineered to serve as the critical link between you and your guitar. Our most popular acoustic guitar strings, EJ's are precision wound with corrosion resistant Phosphor Bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. The result is long lasting, bright sounding tone with excellent intonation.View larger View largerAnatomy of a D'Addario Phosphor Bronze Acoustic Guitar StringThree components of a D'Addario guitar string work together to create your desired tone: Hex-core, outer wrap wire, and ball-end. It all starts with the core. D'Addario pioneered the use of the Hex Core, and as the name suggests, it is a six-sided high carbon steel core-wire. Each side "bites" into the wire used for the outer winding, creating a tight and consistent bond that keeps the string in tune from end to end. The final component is a D'Addario exclusive: color-coded ball-ends that secure the string in place at the guitar's bridge, allowing for easy string identification and a major reduction in wasteful packaging.Phosphor Bronze92% copper and 8% tin with phosphorous, introduced to string making by D'Addario in 1974 as the first "extended life" strings. Phosphor Bronze is synonymous with warm, bright, and well balanced acoustic tone.Round WoundThe most popular and universal construction, Round Wound strings deliver the traditional textured feel most players are familiar and comfortable with.The Player's ChoiceIdeal for the widest variety of guitars and musical styles, D'Addario acoustic strings are the choice of countless professionals around the world including Dave Matthews, Sheryl Crow, Keith Urban, Blake Shelton, Ryan Adams, and many more!View largerThe D'Addario DifferenceIt all starts with our exclusively engineered and built string winding machines. There is literally nothing like a D'Addario string machine. The combination of the most advanced computer-controlled winding technology and stringent incoming wire inspection delivers unmatched consistency, string after string, set after set. Our passion for and commitment to environmentally responsible packaging and raw materials fuels our continued innovation. Last but not least, every D'Addario string is made in the USA, ensuring the highest quality and performance.

Review: So yes I have been playing off / on all sorts of guitars and guitar synths. Ukulele / acoustic flat wound 5 string bass strings and 6 string non flat wound. phew a lifetime!! These strings definitely have 50 % less string noise. HOWEVER I find these are a heavier tension than what I recall to the same gauge and so on one guitar I de tuned down to D which feels comfortable for that particular Guitar and the other I dropped a whole string down in other words I moved the A string to where the Bottom E strings goes. I had to source another G string as the B string is to loose in the G position. Yes this guitar is a little floppy however its tuned to standard tuning and plays really well for my style of playing. AND thats NOT strumming! I would buy these again! :+]

## Questions & Answers

**Q: My old fingers cant manage heavier gage strings anymore. anybody happy with "extra lights" 10-47's ?  is the ease of play worth the loss in tone?**
A: You might try silk and phosphor 11- 47. They play easily while maintaining the more traditional tone. .115 - 47 silk and steel play well but are very mellow tonally. Alot has to do with the guitar itself and of course personal preference.  Additionally,  you may have to set the guitar up again. The strings will ride slightly lower in the saddle and nut.  And they will not pull the neck as much. No easy way other than trial and error.  I have 17 acoustics and have tried several sets on each guitar before settling on what I like on that particular guitar.  Only 2 of the 17 uses the same strings.  Good luck.

**Q: Anyone using these for fingerstyle blues? What do you think of them?**
A: I only play fingerstyle, and I play blues, jazz, pop...I LOVE these strings. If you're not plugged in you may notice a little less volume. Nothing drastic. They sound a bit more "warm." Slides are sweet. They're not that expensive. (I have used another brand that cost something like $30. They are a little nicer, but I can't afford that luxury all the time.) Try a set. Your fingers will thank you.

**Q: Is the core in of the d'addario eft15 round core?**
A: Down in the product details at the bottom of the page -- "D'Addario Phosphor Bronze strings are precision wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. "

Note the "hexagonally shaped, high carbon steel core" so NOT a round core.

**Q: Wait a second, the title for the item is flattened, the description page says roundwound, and one of the answers says they are halfwound. Which is it?**
A: They are flattened. Flat round is a different type of string. Basically its like the small humps of the round string are ground down .

### ⭐⭐⭐⭐⭐ Review
*by M***R on 13 January 2025*

These are my favorite strings for my acoustic guitars. They are very quiet due to the milling of the string windings (not as much 'string-screech') They aren't quite as bright as regular string sets but just right for my style of playing- soft mellow jazz (need brightness, turn on the amplification). I would say they last a bit longer with a little care; cleaning and lubricating them every so often. They are more expensive than the regular sets of strings but are well worth it.
