My first guitar was a Robertson Acoustic.
I loved the tone and play-ability, as well as the fact it seemed to stay in tune even if I didn't play it for a while.
I'm no guitar guru, but I think I got a great deal on it at a used guitar shop for $100.00 in 1984.
Mine got smashed by an angry ex, and I have been wanting to replace it for a long time but can never find anyone else who had ever heard of them.
