Intermediate ABS Resin Oboe with Superb Intonation and Clarity Step up to a spectacular intermediate instrument with the YOB-441AT from Yamaha! This second-generation model is not only made entirely from durable ABS resin but also boasts several upgraded features such as a new bell design, a 3rd-octave key, a low Bb resonance key, and metal tenon joints, to name a few. But unlike the original model, the YOB-441AT is crafted using all-plastic upper and lower joints, which significantly improve the instrument's longevity and prevent issues that can arise with wooden instruments. Additionally, the YOB-441AT allows you to start exploring new fingering techniques with a modified conservatory key system.
