Selling due to replacement. Yamaha Custom Oboe yob831 Purchased in 2011 and used regularly. This is a very good instrument and has never cracked. I have worked with a repairman in Tokyo to make improvements, resulting in an instrument with excellent tone, responsiveness, and ease of playing. It can handle any style of music. For this reason, the second octave tone hole and H key have been replaced with custom parts. The thumb rest has also been replaced with an adjustable one. The original parts will be included if desired. It has been adjusted and is ready to play immediately. I will pack it carefully, but I cannot be responsible for any adjustments that may be needed during shipping. Please refrain from purchasing if you are overly concerned about this. Please do not ask for a price reduction. Feel free to ask any questions you may have in the comments.
