DR StringsSunbeam Phosphor Bronze Medium Lite Acoustic Guitar Strings
1/3
Independent shopping perspective
The Korena take
Phosphor bronze acoustic set in medium light gauge. For players who want warmer strings than 80/20 bronze without the stiffness of full mediums.
Strong match
Who this is for
- Fingerstyle and flatpicking on the same guitar
- Dreadnoughts that sound harsh with 80/20 bronze
- Players stepping up from lights wanting more volume
Consider the trade-offs
When to look elsewhere
- Vintage or small-body guitars built for light gauge only
- Players who want maximum brightness — 80/20 bronze is sharper
- Electric or classical guitars; bronze needs a steel-string 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
Medium lite gauge
Sits between light and medium. More volume and low end than lights, less finger pressure than full mediums.
Detail 03
Sunbeam round core
Round core rather than hex. Tends to feel more flexible and bend easier than a hex-core string of the same gauge.
Detail 04
Acoustic guitar strings
Bronze windings need a magnetic-free environment. They will not drive an electric pickup properly.
Detail 05
Full set
Six strings, all six replaced at once. Mixing new and old strings gives uneven brightness across the neck.
Final check
Know before you order
- 01Heavier than lights — a truss rod tweak may be needed after switching

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 stronger mids and tends to last longer. 80/20 is brighter and more scooped, but fades faster.
02Is medium lite too heavy for my guitar?
Most full-size steel-string acoustics handle it. Small-body, parlor, or vintage guitars specified for light gauge should stay on lights.
03Can I use these on an acoustic-electric?
Yes if it uses an undersaddle or microphone pickup. Guitars with a magnetic soundhole pickup need steel-wound strings instead.
04How many strings come in the pack?
A full six-string set. Nothing else is included — no picks, winder, or cutters.
