The YOB-431M offers a rich, warm tone and precise intonation, making it suitable for both practice and performance. Its ergonomic key design, based on Yamaha’s Custom models, ensures comfortable playability. The Duet+ construction addresses common issues in wooden wind instruments by forming a protective layer next to the air column, improving precision and stability of the bore.
