Yamaha YOB-431MBE Oboe

Precision-crafted for a warm tone, superb playability and longevity, the Yamaha YOB-431MBE Oboe features a semi-automatic octave system with thumbplate. The YOB-431MBE Oboe also features Yamaha’s patented Duet system – a precisely shaped ABS resin insert sits within the grenadilla tonewood of the upper joint, eliminating disadvantages of an all-wood body without losing the grenadilla’s characteristic tone.

Duet System

Using patented technology, the injection-molded inner bore is designed to resist cracking while also stabilising 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.

The result is an incredible oboe which looks and sounds like an all-wood instrument but has improved playability, consistency and durability.

Tone Holes

Upper-joint tone holes (except metal octave vents) are molded simultaneously with the resin bore.

Joint Tenon

The upper joint tenon is also formed as an extension to the resin bore. This ensures smooth connection between the joints even under moist conditions.


The gold coloured trademark logo is stamped on the back of the upper joint.
