Made using the same processes as custom models, it is a high-cost-performance model with professional sound quality, accurate intonation, and well-balanced playability.

The 431 has a semi-automatic octave key system, and the exquisite balance of the keys, each individually adjusted by experienced craftsmen, fully brings out the musician's musicality and expressiveness.
