Galli's uniquely formulated Carbon treble strings offer bold projection and quick response while allowing for the production of warm, elegant, clear sound, strong fundamentals, beautiful overtones and resonance. As with all carbon strings, these slightly opaque colored strings are somewhat thinner than traditional nylon strings. Galli Genius Carbonio trebles come with Genius bass sets featuring Galli's unique Pro-Coated polymer process, further assuring superior quality and richness of sound.
