This is an innovative ligature from a cutting-edge Italian brand. The structure, named the "Z machine," connects the screw section and resonator (reed pressure plate) with two strings, which allows the force pressing down on the reed to be applied evenly, resulting in a well-balanced sound from low to high notes. In addition, multiple materials are available for each part, allowing for a wide range of models to be created by combining them. The resonators can be purchased separately (scheduled for sale) and are easy to replace, allowing for a wide variety of sound creation. ■ Type: reverse tightening ■Material: Brass (Z machine) / Brass (resonator) ■Finish: 24K gold plated (Z machine) / Unlacquered (resonator) ■Accessories: Outer box ■Compatible mouthpieces: Selmer, Otto Link, and other rubber mouthpieces of similar size *Cap is not included. *The strings are made to be slightly tight. First, remove the resonator, attach the mouthpiece without a reed, and tighten it once to stretch the strings, making it easier to attach them later.
