yamaki guitar question?

[samm]

First, I'de like to say how much I enjoy the forum. I've found all you folks really informative as well as entertaining. Aside from my recently aquired OM 03 MQ, I have had a Yamaki 12 string for a number of years. She plays and sounds great. Even some buddies that are way better players than I'll ever be agree. The thing is, I know nothing about the model. I've been on countless sites and have found plenty of other Yamaki models but nothing on my AY 474 S. I would really appreciate information that the great and wise forim members may have.         Steve
