Detail 01
Resophonic gauging
Heavier overall than a typical acoustic set, so the cone gets enough drive and open tunings hold pitch.

Independent shopping perspective
The Korena take
Phosphor bronze set built for resonator guitars. For players running a squareneck or roundneck resonator who need the tension that design expects.
Strong match
Who this is for
- Resonator players in open tunings like G or D
- Squareneck slide playing where high tension matters
- Replacing a worn set on a dobro-style instrument
Consider the trade-offs
When to look elsewhere
- Standard flat-top acoustics — the gauging is built for a resonator
- Electric guitar, where bronze windings won't drive the pickups
- Players wanting a light, easy-bending feel
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 than 80/20 bronze and slower to go dull, which suits the metallic edge of a resonator cone.
Detail 03
Higher tension
Feeds the spider or biscuit bridge properly. Too little tension and the cone sounds thin and undriven.
Detail 04
Built for slide
Higher tension resists the bar pressing strings down onto the frets, keeping notes clean under a slide.
Detail 05
Bronze windings
Non-magnetic, so these belong on an acoustic resonator, not an electric or a magnetic-pickup instrument.
Final check
Know before you order
- 01Fitting these to a standard acoustic adds significant tension — not recommended
- 02Confirm whether your resonator takes ball-end strings before ordering
- 03One set only. No slide, bar, or setup tools included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use these on a regular acoustic guitar?
Not advised. Resonator sets run heavier to drive a cone, and that extra tension on a flat-top acoustic can stress the neck and top.
02Do these work for open G tuning?
Yes. That's a standard resonator tuning, and the heavier gauging keeps tension sensible even with strings tuned down to it.
03Squareneck or roundneck?
Both. Squareneck players benefit most from the higher tension under a bar; roundneck players who play both slide and fretted also use resonator sets.
04How often should I change them?
Depends on hand chemistry and playing hours. Change when the wound strings go dull or intonation starts drifting up the neck.
