What makes the Versa-X different from the original Versa? Well, it's a Next Generation product! That means it employs Rovner's patented Mass Loaded Technology, as evidenced by the new-style metal insert and the unique resonating ribs feature.
The DUO ligature by BG is made for rubber or plastic mouthpieces. It is available for soprano, tenor, and alto saxophone and Bb Clarinet. This ligature grips perfectly on cane or synthetic reeds. It was carefully designed to reduce contact with the mouthpiece to produce the maximum vibration.
