I bought my Grammer in the early 70's. In Costa Mesa Cal. Of course it was used. I paid $500.00 for it. It's a G-10 serial # 7395. It has aged very well and sounds excellent plus it's in beautiful shape. I play it about 4 times a week. It is easy to play and I'm so happy I have one. As far as I know the top is spruce and the back and sides are rosewood.
