The Augustine strings were the first commercially available nylon guitar strings, and over the last five decades Augustine has consistently remained one of the leading string manufacturers in the world. The Traditional strings are a refinement of these early strings that helped to transform the sound of the guitar in the middle of the 20th century.
The Blue Label is their highest tension, so the Blues tolerate a stronger stroke before the sound breaks up. They are also a bit brighter, but not quite as sweet.
Basses: These basses start life with a brilliant edge and tend to grow into a richer, warmer sound after some play. Their lifespan is average and they take longer than average to settle into tune. However, the intonation is excellent and they allow for a great deal of color variety. They have excellent projection.
Trebles: The trebles are sweet and warm with a bright core. They are quite flexible and project well. There is also a great deal of color variety among the three strings. Their intonation is, however, more inconsistent than average, and it sometimes takes a couple of sets to get a perfectly true string. They also take longer than average to hold their pitch. Once you`ve found a good one, though, it has excellent longevity.
