Detail 01
80/20 bronze
Bright and crisp when new, but the top end fades faster than phosphor bronze as the alloy oxidizes.

Ernie Ball2012 Earthwood 80/20 Bronze 12-String Medium Acoustic Guitar Strings
1/2
Independent shopping perspective
The Korena take
Medium-gauge 80/20 bronze strings for 12-string acoustics. A budget restring set for players who want a bright, ringing top end.
Strong match
Who this is for
- Players restringing a 12-string that has gone dull
- Anyone wanting a brighter, more chiming 12-string sound
- Keeping spare sets on hand for gigs
Consider the trade-offs
When to look elsewhere
- Six-string acoustics — wrong string count entirely
- Players wanting warm, mellow tone; phosphor bronze suits that better
- Light-gauge fans who find medium too stiff to bend
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
12-string set
Includes the octave and unison pairs. A 6-string set will not cover a 12-string.
Detail 03
Medium gauge
More volume and low end, higher tension. Harder on the fingers than lights.
Detail 04
Ball end
Standard fit for a bridge with pins. Not for classical-style tie-block bridges.
Final check
Know before you order
- 01Medium gauge raises total tension — check your guitar handles it before switching up
- 02Gauge changes usually mean a truss rod and intonation check
- 03One set only. No picks, winder, or extras included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit any 12-string acoustic?
They fit standard steel-string 12-strings with a pin bridge and ball-end strings. Check that your guitar is rated for medium gauge before installing.
02How are these different from phosphor bronze?
80/20 bronze is brighter and more cutting when fresh. Phosphor bronze is warmer and holds its tone longer. On a 12-string, 80/20 emphasizes the shimmer from the octave strings.
03Can I use medium gauge if my guitar came with lights?
Often yes, but tension goes up noticeably. Watch for higher action and a bowed neck. A setup after the change is a good idea.
04How many strings are in the set?
Twelve — six main strings plus their octave and unison partners.
