This is a Yamaha YOB-831 semi-automatic oboe with gold plating. Purchased in October 2024, the current list price as of October 27th is 1,780,000 yen. It's ready to go and can be used immediately in performance. I have played this instrument extensively as principal oboe in regular concerts and commissioned performances with orchestras that are full members of the Japan Orchestra Federation. I've also played solos in front of orchestras. I tested and selected this particular instrument before purchase, using it in important performances multiple times. It has a meltingly smooth blowing feel, and even among Yamaha instruments, which are generally neutral, this one has absolutely no quirks. It has smooth slurs, is very strong in pianissimo, and the low register, which can be difficult on the oboe, is very easy to play. It can also produce a considerable ff (fortissimo). It is equipped with an F resonance key, which is not found on standard 831 models, and corrects the intonation of the F, which tends to be flat. The gold plating is also recommended for those with sweaty hands. There is a slight crack in one place below the third octave key. It has been beautifully repaired, and the current airtightness is perfect. This is a superb instrument that can withstand the demands of professional use. Please experience the true potential of a Japanese-made instrument. *The humidification case in the photos is not included. Thank you very much.
