## 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 N***E on 7 January 2025*

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! :+]
