Phosphor bronze
Phosphor in the alloy slows corrosion and warms the tone. Less zing than 80/20 bronze, more midrange body.

DR StringsRare Phosphor Bronze Medium Heavy Acoustic Guitar Strings
1/3
Independent shopping perspective
The Korena take
Phosphor bronze acoustic strings in a medium-heavy gauge. For flatpickers and strummers who want volume and a warm midrange over easy playability.
Strong match
Who this is for
- Hard strumming and flatpicking where light gauges sound thin
- Dreadnoughts and jumbos that can carry the extra tension
- Players wanting a warmer tone than 80/20 bronze
Consider the trade-offs
When to look elsewhere
- Fingerstyle players who want a light, forgiving touch
- Parlor or small-body guitars not braced for heavy tension
- Vintage or lightly built instruments
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
Medium heavy gauge
More tension than a standard light set. Louder and fuller, but harder to bend and more work on the fretting hand.
Detail 03
Uncoated
Brighter out of the pack than a coated set, but sweat and skin oils dull them faster. Wipe down after playing.
Detail 04
Acoustic set
Bronze wrap needs a magnetic pickup to be silent — these will not drive a standard electric pickup properly.
Final check
Know before you order
- 01Heavier tension usually needs a truss rod tweak if you are stepping up from lights
- 02Confirm your guitar is rated for medium or heavier gauge before stringing up
- 03Ball ends need bridge pins, which are not included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between phosphor bronze and 80/20?
Phosphor bronze is warmer with more midrange and resists corrosion longer. 80/20 is brighter and more scooped but dulls faster.
02Are these too heavy for my acoustic?
Medium heavy puts more pull on the top and neck than a light set. Check the maker's recommended gauge, especially on small-body or older guitars.
03Will these work on an electric guitar?
No. Bronze is not magnetic enough for electric pickups. Use nickel or steel electric strings instead.
04Do I need a setup after switching gauge?
Usually yes. Going up in gauge adds relief to the neck and can raise action. A truss rod adjustment brings it back.
