Optimus if I’m not too mistaken that looks like makeover of the Realistic EQ that I have, well it’s at friends still pending fixing not that it matters my friend is lazy bugger otherwise he would have fixed it 3 years ago.

The design of that EQ first came around I think mid 1980’s.
It was replaced with the Genexxa which I have and was also featured in science fiction flick Contact 1997.
I like the led layout of the display easy to see with green amble red lights. The Genexxa is pale looking display green which I don’t like.
