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
Custom light gauge
Lighter than a standard light set. Less finger pressure, easier bends, a bit less low-end push.
Detail 03
Single set
One guitar's worth of strings. Good for trying the alloy before buying in bulk.
Detail 04
Acoustic construction
Bronze winding over steel core. Designed to move an acoustic top, not a magnetic pickup.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between 80/20 and phosphor bronze?
80/20 bronze is brighter and more cutting out of the pack. Phosphor bronze is warmer and keeps its tone longer.
02Is custom light too light for a dreadnought?
No, it works fine. You'll get a slightly softer, less powerful sound than a light or medium set.
03How many strings are in a set?
Six — one full set for a standard six-string acoustic.
04Do these work on a 12-string?
No. A 12-string needs a dedicated 12-string set with the correct octave pairs.
