D'AddarioEJ14 80/20 Bronze Bluegrass Medium Light Acoustic Guitar Strings
1/9
Independent shopping perspective
The Korena take
80/20 bronze acoustic strings in a medium light bluegrass gauge. For flatpickers who want volume and bright attack from a steel-string acoustic.
Strong match
Who this is for
- Bluegrass flatpicking where the guitar has to cut through a jam
- Players who want maximum brightness right out of the package
- Dreadnoughts and larger bodies that can drive heavier bass strings
Consider the trade-offs
When to look elsewhere
- Players who want warm, mellow tone — phosphor bronze suits that better
- Classical or nylon-string guitars; steel strings will damage them
- Anyone who wants tone to stay consistent for many weeks
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
Bluegrass gauge
Light treble strings with heavier bass strings. Easier bends and leads on top, more power and volume below.
Detail 03
Medium light overall tension
Sits between light and medium sets. Enough push to drive a big top without the stiffness of full mediums.
Detail 04
Acoustic steel strings
For steel-string flattops only. Never install these on a classical or nylon-string instrument.
Detail 05
Single set packaging
One complete six-string set. Buy multiples if you change strings frequently or need spares on gigs.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between 80/20 bronze and phosphor bronze?
80/20 bronze is brighter with more zing and a scooped midrange. Phosphor bronze adds phosphor for a warmer tone and longer-lasting brightness. 80/20 dulls faster.
02Why are these called bluegrass gauge?
The set combines light treble strings with medium bass strings. Flatpickers get easier bending on top while the low strings deliver the volume that bluegrass rhythm playing demands.
03Can I use these on my classical guitar?
No. These are steel strings. Classical and nylon-string guitars are not built for steel-string tension and will be damaged.
04Will these work on a small-body acoustic?
Yes, though smaller bodies do not project the heavier bass strings the way a dreadnought does. The tension is manageable on most steel-string flattops.
