D'AddarioEFT15 Flat Top PB Extra Light Acoustic Guitar Strings
Independent shopping perspective
The Korena take
Phosphor bronze acoustic set with a flattened winding surface, in extra light gauge. For players who want easy fretting and less finger noise.
Strong match
Who this is for
- Fingerstyle players who record and hate squeak on string changes
- Beginners whose fingertips are still toughening up
- Smaller-bodied acoustics that get boomy with heavy gauges
Consider the trade-offs
When to look elsewhere
- Heavy strummers who want maximum volume and low-end push
- Players who bend hard — extra light can go sharp under pressure
- Anyone needing a set for electric or classical guitar
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
Phosphor bronze
Warmer and less brash than 80/20 bronze, and it holds its tone a little longer before going dull.
Detail 03
Extra light gauge
Lowest tension of the common acoustic gauges. Easier to fret and bend, quieter and thinner sounding.
Detail 04
Smoother surface, not flatwound
Keeps most of the brightness of a round-wound string while cutting the finger noise a polished surface reduces.
Detail 05
Acoustic set
Bronze windings are non-magnetic. These will not drive a standard electric pickup properly.
Final check
Know before you order
- 01Going from light to extra light reduces neck tension — check relief and buzzing
- 02Lower tension can make the action feel low enough to rattle on a flat setup
- 03Strings only. No winder, cutter, or bridge pins included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these work on a guitar with an undersaddle pickup?
Yes. Undersaddle and soundhole magnetic systems differ — piezo pickups read vibration through the saddle and work fine with bronze strings.
02How are these different from regular phosphor bronze?
The winding surface is flattened rather than fully round. Same core material and warmth, noticeably less squeak when your hand moves along the neck.
03Are they good for a beginner?
Yes. Extra light gauge means low tension, so fretting chords takes less hand strength while your fingertips build up.
04Will extra light gauge sound too thin?
On a large dreadnought played hard, likely. On smaller bodies and for fingerpicking, the lower tension usually balances well.
