Yamaha Model YOB-441IIMT 'Duet' Intermediate Grenadilla Oboe BRAND NEW

Yamaha YOB-441IIMT Oboe Overview

The Yamaha YOB-441IIMT is a C oboe from Yamaha’s renewed 441T series, updated with added keys and ergonomic refinements for more comfortable performance. Built from aged and seasoned Grenadilla wood and crafted in a manner similar to Yamaha Custom models, it pairs a professional-style tonehole design with Yamaha Duet Plus technology: an ABS resin-lined inner bore and tone holes that help reduce moisture absorption and improve stability through temperature and humidity changes while preserving the acoustic character of a predominantly wooden body.

Who the YOB-441IIMT Oboe Is For

The Yamaha YOB-441IIMT is an intermediate C oboe designed for advancing players who want a more professional-style feel, response, and tonal complexity without stepping into a full Custom model. Its aged Grenadilla construction supports a focused, resonant oboe tone, while Yamaha’s Custom-style tonehole design is intended to promote even response and accurate intonation across registers.

This model is especially well suited to students transitioning into conservatory-style technique, serious ensemble players, and doublers who need stability in varying environments. The 441T update adds a third octave key to reduce register-change effort and improve comfort in demanding passages, and Duet Plus helps limit moisture-related changes by coating the wooden bore and tone holes with ABS resin while preserving the sound and resonance of a largely wooden instrument.

Common Questions About the Yamaha YOB-441IIMT

What does “Duet Plus” mean on the Yamaha YOB-441IIMT?

Duet Plus is Yamaha’s patented construction that coats the wooden inner bore and tone holes with ABS resin and uses an injection-molded resin inner bore section in the upper joint, helping reduce moisture absorption and improve durability through temperature and humidity changes while retaining a predominantly wooden acoustic structure.

What is the main difference between the 441T series and earlier 441 models?

The renewed 441T series adds keys and features for improved performance comfort, including a third octave key, which can make high-register response and register transitions feel less stressful for the player.

Is the Yamaha YOB-441IIMT suitable for serious ensemble and pre-professional use?

Yes. It is an intermediate oboe built from aged Grenadilla with a Modified Conservatoire system, semi-automatic octave mechanism, and professional-style tonehole geometry, making it appropriate for advanced students and demanding school, orchestra, and chamber settings.
