## Overview

D'Addario EFT17 Flat Tops are medium gauge (13-56) phosphor bronze acoustic guitar strings, precision wound and polished for a smooth feel and balanced semi-bright tone. Made in the USA, these strings reduce finger noise and offer durability and volume ideal for recording and live performance, trusted by musicians for over four decades.

## Description

As a half round phosphor bronze acoustic guitar set, Flat Tops are designed to significantly reduce unwanted finger noise. Combining tried-and-true phosphor bronze tone with a smoother feel and quieter playing experience, they’re excellent for recording—and slide guitar playing. Flat Tops are made with a high carbon steel core and phosphor bronze wrap wire, which is then precision ground and polished, leaving behind a semi-flat string with a smooth feel and beautifully balanced tone. 13-56 Medium gauge strings provides maximum volume and projection, with more tension and resistance.

Review: Guitar time - Great strings play alot of blues these strings hold up and just very nice to play and they sound bright luv them.
Review: The best strings for acoustic electric guitars - I play an acoustic electric. When I first got an AE 12 years ago I was dismayed at how much string squeak was amplified. In desperation, I tried flat wound strings for electric guitars. That reduced the string squeak significantly, but the tone was flat and tinny. Then I discovered D'Addario Flat Tops. They are round wound, but with the tops of the round wire shaved off. There is a little more string squeak than with flat wounds, but the tone is as good as a good round wound. I've used nothing else for over 10 years. I've tried both the medium and light gauges. My playing style works better with the medium gauge -- which is a rather "heavy" medium. The strings are also very durable, with a set lasting several months with regular playing. Only once have I broken a flat top string while playing. Given the increasing popularity of acoustic electrics, I don't understand why these strings aren't more common.

## 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 .

### ⭐⭐⭐⭐⭐ I was surprised
*by D***T on July 19, 2013*

There are plenty of folks who tried these and then seem to hate these. I found them a very interesting change from EJ16s. I usually play without a pick so these strings with a pick sound pretty good to me but I also changed to medium weight at the same time. Surprisingly enough, they don't seem harder to fret than EJ16 light strings. Also surprising was that they are not ground very flat. To my ear they reduce the squeak from sliding on the bass strings about a third but certainly do not eliminate it. My opinion is that technique has more effect on string squeak than these flattened strings but they provide a very different playing experience and tone and were worth trying out. Time will tell if they grow on me.
