Up for sale is a Yamaha 821 oboe, full conservatory system with 3rd octave key, this instrument has everything you need! This oboe got me through my college undergrad years and I've since upgraded and it's time for this beauty to find itself a new home:) there are 2 cracks in the upper joint that have been fixed, one with proper professional glue and one with 2 carbon fiber rings to prevent any further cracks. Cracks did not affect sound whatsoever.
