Nylon concertgitaar snaren (medium tension) van de hoogste kwaliteit, sinds 1947. Augustine is op het klassieke snarengebied wereldwijd een grote naam, staat ook bekend als 'The Superior Concert String'. 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. Trebles: The trebles are bright and brilliant, and they have excellent projection. The three trebles are more consistent with one another than average, and their intonation is quite consistent. They hold their pitch quickly, and can tolerate very loud playing. The Red Label is a lower tension than the Blue, but the two are close. Moreover, the Regal trebles are more taut than their traditional Red Label counterparts and are more on a par with the Traditional Blue Label tension.
