What matters in use
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 01
Significantly more tension than a light set. Drives the top harder for volume, but the fretting hand works more.
Detail 02
Warmer and more midrange-forward than 80/20 bronze. Suits heavy strumming without turning harsh.
Detail 03
Seals the windings against sweat and grime, so the set holds its tone months past uncoated life.
Detail 04
Pulls harder on the top and neck. Some older or lightly built guitars are not rated for medium strings.
Detail 05
Slicker under the fingers and quieter on position slides than bare bronze.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
On a solidly built modern dreadnought, no. Older, small-bodied, or lightly braced guitars can be strained by the extra tension — check what the builder specifies before stringing up.
Medium (.013-.056) for volume and hard strumming. Custom light (.011-.052) for easier bending and a lighter touch. Medium is harder on the fingers.
The NANOWEB coating keeps sweat off the windings, so tone lasts far longer than uncoated phosphor bronze — commonly months rather than weeks.
No. These are steel strings for steel-string acoustics. A nylon-string classical guitar is not built to handle steel string tension.
