The JY84SB is the K Yairi version of a full size Jumbo. The spruce top, coral rosewood back and sides combination gives power, projection and a superbly balanced and rich sound. The sunburst finish is absolutely stunning, beautifully executed in terms of aesthetics. The sound hole is decorated with two rings of tinted maple and abalone. This is a big guitar, but is so comfortable that people of all sizes and shapes appreciate it. Perhaps primarily a strummers guitar, because the sound is so balanced, perfect for accompanying vocals. All the qualities of a K Yairi guitar, in XXL format.
