Hello All...Ya know, a lot of us probably really don't pay attention to the serial #s on our instruments. And we should. Even if it means simply jotting them down on a piece of paper and hiding it in your sock drawer for some sort of future reference. Anyway... I was doing just that, about 10 minutes ago, and realized I have a black Dimension IV of which the serial # starts with the number 4. So now I am thinking this guitar may have been made and possibly marketed in 1984. If this is true... this bumps the availability (of the Dimension IV) back another year, 1984 instead of 1985. Just wanted to share this with you... Steve.
