Description from Amazon USA :
The H-Ligature & Cap was conceived as a "retro" version of the famous Harrison ligature used by many of the worlds greatest clarinetists and saxophonists, Rico's H-ligature offers the sought-after features of this popular design.
The new H-ligature holds the reed firmly to the table of the mouthpiece assuring better contact and therefore reducing leaks along the siderails. Additional support has been added to the ligature brackets to increase durablity.
At its San Fernando Valley facility, Rico has a state-of-the-art reed research center, and employs the collaboration of agronomists, scientists, and musicians to produce top-quality reeds that include Rico Reserve premium reeds for clarinet and saxophone. Rico reeds are designed to benefit all levels of musicians from the beginner to the seasoned professional. Many of the world's finest clarinetists and saxophonists use Rico brand reeds, such as Anthony McGill, Mark Nuccio, Jessica Phillips, Jerry Bergonzi, Chris Potter, Benny Golson, Ernie Watts, Bob Sheppard, Walter Boeykens, Seiji Yokokawa, Philippe Geiss, Diastema Saxophone Quartet, and many more.
