Yamaha 441 Intermediate Grenadilla Oboe with Plastic insert in upper joint

The Yamaha YOB-441M oboe achieves a clear sound quality and superb intonation by dramatically improving the precision and stability of the bore. Also to cope with various durability issues inherent in wooden wind instruments, the YOB-441M employs innovative techniques to form a protective layer next to the air column. The combination of precious wood and state-of -the-art resin preserves quality sound while improving durability.

Using patented technology, the injection-molded inner bore is designed to resist cracking while also stabilizing the bore, which adds consistency and durability. 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. is made of the finest quality aged and seasoned grenadilla wood for a rich professional sound. This is the same material as used on Yamaha's Custom models and has been carefully crafted in a similar manner. The size and placement of the toneholes is also the same, giving even and accurate intonation.

The 441M features a simplified conservatoire semi-automatic octave system and includes a left-hand F key, Fork F resonance key and a low Bb key. Trill keys are C#-D#, F#-G#, Ab-Bb, A#-B, B-C#, left C-D, right C-D. It has 8 cork and 15 felt pads, and silver-plated nickel silver keys.
