Medium gauge
Higher tension. More volume and stronger bass, but harder on fingers and less forgiving for bending.

D'AddarioEJ17 Phosphor Bronze Medium Acoustic Strings 3-Pack
1/7
Independent shopping perspective
The Korena take
Three sets of medium-gauge phosphor bronze acoustic strings. For players who go through strings fast and want volume and low-end over easy bending.
Strong match
Who this is for
- Strummers who want more volume and body from a dreadnought
- Players restringing every few weeks who want spares on hand
- Open tunings and drop tunings that need higher tension
Consider the trade-offs
When to look elsewhere
- Fingerstyle players who want a light touch
- Small-body or vintage guitars braced for lighter tension
- Anyone doing heavy string bending on an acoustic
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 darker than 80/20 bronze, and it holds that tone longer before going dull.
Detail 03
3-pack
Roughly a third off single-set pricing per set. Worth it only if you restring regularly.
Detail 04
Acoustic-specific
Wound on bronze alloy for acoustic projection. Will not drive an electric guitar's magnetic pickups.
Final check
Know before you order
- 01Medium tension can raise action and need a truss rod tweak on some guitars
- 02Check your guitar's recommended gauge before jumping up from lights
- 03No picks, winders or cutters included — just the three sets
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this the same as EJ17 sold as a single set?
Yes, three sets of the same medium-gauge phosphor bronze strings, packaged together.
02Will medium gauge damage my acoustic?
On most steel-string acoustics, no. On lightly braced small-body or vintage instruments, the added tension is a real concern — check with the builder.
03Can I use these on a classical guitar?
No. Classical guitars need nylon strings; steel string tension can damage the neck and bridge.
04How long do they last?
Depends on how often you play and how much your hands sweat. Heavy players get a few weeks; occasional players get months.
