Does anyone know anything about this guitar. its built by Yamaha and its old. i got it as a present from an old man and it sounds great with a nice full bodied tone. i cant find this guitar on the net. i can see only Eterna 10 makes on ebay. please help.
I tried to Google it. I got Yamaha EF-15 Eterna :


The right hand side has a picture. Below the Gibson LP.


Some info about it further down.



I think that's the guitar you're referring too. Anyway that's all my Googling got.
