This is an innovative ligature from a cutting-edge Italian brand. The structure, named the "Z machine," connects the screw part and the 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 resonator can also be purchased separately (scheduled for sale; the ebony model requires replacement of the entire string), and is easy to replace, allowing for a wide variety of sound creation. ■ Type: reverse tightening ■Material: Brass (Z machine) / Ebony (resonator) ■ Finish: Unlacquered ■Accessories: Outer box ■Compatible mouthpieces: Selmer, Meyer and other rubber mouthpieces of equivalent size *Caps are 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.
