YAMAHA Yamaha GC-61 Matsu Jacaranda 1994 or 2004 used item. The top plate is German spruce, and the back and sides are Jacaranda. Side plate material Jacaranda. Back plate material Jacaranda. I was told by Yamaha that the production year of this guitar was unknown because there was no serial number, but my own research showed that it was most likely 1994 or 2004.
