This is a proxy listing, so I may not be able to answer questions requiring specialized knowledge. I apologize, but shipping will generally be on weekends and holidays. Please be aware of this when purchasing. This is a Fernandes biwa-shaped bass guitar, the Eikichi Yazawa model. ★YB70 (1982-1989) The Fernandes logo is the "stone logo," so it's likely a YB70 (1982-1989). Other model references: ・FYB70 (1978-1981) ・YB70 (1982-1989) ・YB65 (1990) Comes with a dedicated hard case. It has hardly been used, so the body is clean, with no noticeable scratches, stains, or cracks. Please refrain from purchasing if you are concerned about it being an old model. If you would like to see photos from other angles, please request them in the chat, and I will add them. - Brand: FERNANDES - Headstock Shape: Headstock with tuners - Fretboard Material: Rosewood - Color: Natural - Number of Strings: 4 strings
