Maintained! Original Model 7 You can enjoy the deep, exquisite balance between the glossy mid-high range tone with a high sense of transparency. For analog fans, it's a model that's been over half a century since it went on sale, but it's still one they admire. The lustrous and indescribable tone is a charm that cannot be enjoyed on modern machines. There are scratches and bumps on the exterior. Serial 7-14836 (Satoshi Yonejima)
