Fender70M 80/20 Bronze Acoustic Strings - Medium
Independent shopping perspective
The Korena take
80/20 bronze acoustic guitar strings in medium gauge. A bright, loud set for flat-top acoustics played with a pick.
Strong match
Who this is for
- Strummers who want volume and top-end sparkle
- Dreadnoughts and larger bodies that handle higher tension
- Players who like a bright attack right out of the pack
Consider the trade-offs
When to look elsewhere
- Small-body or vintage guitars not built for medium tension
- Fingerstyle players wanting a warmer, softer response
- Anyone bothered by bronze dulling quickly with sweaty hands
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 gauge
Higher tension than light. More volume and low end, harder on the fingers and on the neck.
Detail 03
Acoustic set
Bronze wrap will not drive a magnetic pickup. Fine for a piezo or mic, not for a steel-string electric.
Detail 04
Ball end
Standard for pin bridges. Seats under the bridge pin the same way as any common acoustic set.
Detail 05
Wound third string
Typical for acoustic sets. Bends on the G feel stiffer than they do on an electric with a plain third.
Final check
Know before you order
- 01Confirm your guitar is rated for medium tension before moving up from light
- 02Changing gauge shifts neck relief; a truss rod check is likely
- 0380/20 bronze goes dull faster than phosphor bronze; buy a few sets
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between 80/20 and phosphor bronze?
80/20 is brighter and more scooped in the mids, with a shorter bright window. Phosphor bronze is warmer and holds its tone longer.
02Will medium gauge damage my guitar?
On a guitar built for it, no. On a small-body or older instrument not rated for medium tension, the added pull can cause problems.
03Can I use these on a classical guitar?
No. Classical guitars need nylon strings and are not built for steel string tension.
04Will these work on an acoustic-electric?
Yes with a piezo or microphone system. A magnetic soundhole pickup needs steel-core strings, which bronze wrap does not serve.
