The YOB431M is made of top quality aged and seasoned Grenadilla wood for a rich 'professional' sound. The 431M has a semi-automatic octave system and the keys are hand-adjusted by experienced artisans for superb playability. The upper joint body is drilled out slightly larger around the bore and tone-holes. Thermoplastic ABS resin is injected into the cavity, instantly forming the inner shape of an oboe. It is designed to preserve as much as 90% of the wooden portion, while its natural appearance is hardly distinguishable from conventional all-wooden models.
Yamaha YOB431M Oboe
Yamaha oboes have achieved clear sound quality and sperb intonation by dramatically improving precision and stability of the bore. Also to cope with various quality issues inherent in wooden wind instrumentsm Duet+ models employ innovative techniques to form a protective layer next to the air column. The combination of precious wood and state-of-the-art resin is not simply a "Duet" of tradition and technology - it's a "Plus" advantage indeed!
