Yamaki guitars were well made, and many had solid tops. The bracing is a copy of a Martin D28, as is the body size. The scale is a bit shorter than Martin, 640mm vs 645mm. The interior bridge plate is rosewood, indicative of high quality. Cheap guitars have spruce. One thing I don’t like is the thick lacquer on the top. I might strip it off, which should improve the tone. A poor man’s D28 for about $50 after I buy tuners and strings.
