I used to have one of these in college. I couldn't play it then ant it still seems ridiculous. It made some very cool sounds though. I got mine for about $1,500 or so as I recall, from a guy in Ardmore, Pa. He was desperate for money, I had some and I rapidly became the coolest guy in my dorm. I had the tron as well but this had way more knobs and sounded much more "trippy." I sold it a few months after buying it cause I was to stupid to figure out how to play anything constructive except the parts from "Lucky Man" and a few other ELP bits and pieces. Now, if I had it, I'd buff it up nice and shiny and make it go ooooooeeeeeoooooweee oooweeeooooweeeooooounnnnggggggggggg
