The interior has been thoroughly reviewed and brushed up! The condenser was replaced with an oil condenser, and the sound loss and stretch were greatly improved. The warm, glossy sound goes well with stringed instruments and creates a vivid sound. The exterior has dullness, scratches, etc. Also, the hood is slightly distorted (Yonejima Satoshi)
