Francois Louis Ultimate S Alto Ligature & Cap
Thanks to the resonating pipes this ligature generates a range of sympathetic vibrations that enrich the player's sound. This model fits the following metal mouthpieces: Selmer, Dukoff, Berg Larsen, Ponzol, Jody Jazz, Yanagisawa and Guardala (may need the level expander. Will fit a vintage Guardala tenor).
