The stainless steel wires of the Original Ultimate have been replaced by a Brass Brace. Its suppleness makes it fit your mouthpiece smoothly. The tightening is assured by a single Top Screw for a great comfort of use. The contact with the reed is assured by a Solid Brass Pressure Plate providing more resistance and a centred resonance. The Longitudinal Contact with the Mouthpiece by Brass Resonators and Rolls guarantees free Vibrations of the ensemble Reed / Mouthpiece. All this produce a deeper tone with a well balanced resistance and a great projection. The Pressure Plates Set of the Original Ultimate Ligature can also be used with the Ultimate Ligature Pure Brass.
