// AIZEN SO for Alto Sax // This model reproduces the short shank model of the Selmer Soloist, a vintage mouthpiece that remains popular among many players. The Aizen SO mouthpiece's narrowed horseshoe-shaped chamber produces a warm, crisp tone, smooth breathing, and excellent response, achieving the high-quality sound required in both classical and jazz music. Aizen has corrected the low-end blockage that often occurs with vintage mouthpieces, and has recreated the distinctive vintage sound with a stress-free playing feel and well-balanced sound across the entire range. The details have been revised and evolved into the Mark II!■Accessories: outer box, pouch ■Opening "C*" (1.70mm)...Mayer 4, between Selmer C** and D, equivalent to Dukoff D4.
