Regal (high tension) treble strings with Red (medium tension) bass strings
A major accomplishment in the science of sound. The Regal guitar strings are composed of a new and unique polymer, one which guarantees brilliant, projecting sound and clear bell-like tones. No matter what instrument or style of music you play, you will find that Regals will complement it. Regals are a heavy-gauge treble string. Augustine's Red bass strings are copper wound for a medium string density and tension.
