I've come across this twierd old thing called a Gizmotronic. I've never seen or heard of it, but now, all of a sudden, I have one. Does anyone know anything about this thing? I'll get some pictures of it ASAP, but for now I'll just describe it: It's a black box that appearantly you install right near your bridge. There are four keys that you depress to push little rubber wheel down onto your strings. The wheels have teeth, and when they rotate on your strings, they are supposed to sound like an bowed instrument. This one's never been installed, is in the original box, with all the original documents, including the decal, carrying bag, and "Introduction to the Gizmotronic" 33. I'm thinking this thing is from the early 70s, judging by the look of it and the documents and all. Can anyone help? This is odd!
