CleartoneCoated Phosphor Bronze Medium Acoustic Guitar Strings
Independent shopping perspective
The Korena take
Coated phosphor bronze medium set. The loudest and stiffest of these three. For strummers and flatpickers with developed hands.
Strong match
Who this is for
- Hard strumming and flatpicking where you need volume
- Dreadnoughts and jumbos that need tension to open up
- Players who want strong low end for bluegrass or rhythm work
Consider the trade-offs
When to look elsewhere
- Beginners — medium gauge is hard on untoughened fingertips
- Small-bodied or vintage guitars not braced for medium tension
- Fingerstyle players who want a light, responsive touch
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
Copper and tin with phosphor added. Warm, slightly darker than 80/20 bronze, and slower to corrode.
Detail 03
Coated
A thin layer over the wire slows corrosion from sweat, so the tone stays consistent longer than an uncoated set.
Detail 04
Acoustic guitar strings
Bronze windings drive a wooden top. Electric pickups won't read them properly.
Detail 05
Tension on the neck
Mediums pull harder than lights. Some older or lightly braced guitars are only rated for light gauge.
Final check
Know before you order
- 01One set of six strings. No winder, picks or bridge pin puller included
- 02Check your guitar is rated for medium tension before fitting these
- 03Going up from lights raises action and pulls the neck — expect a truss rod tweak
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I put mediums on any acoustic guitar?
Not always. Some smaller or older guitars are built for light gauge only, and medium tension can pull the top or bow the neck. Check what the maker specifies.
02What's the difference between these and the ultra lights?
Gauge. Mediums are thicker, so they push more volume and low end but need more finger strength. Ultra lights are easier to play but quieter and thinner sounding.
03Do I need to adjust my guitar after switching to mediums?
Likely. Heavier strings pull the neck forward and raise the action. A truss rod adjustment and intonation check will bring it back.
04Phosphor bronze or 80/20 bronze?
Phosphor bronze is warmer and darker, and holds its tone longer. 80/20 is brighter and more scooped when new. Phosphor suits most players who don't want to change strings weekly.
