I had the Casio VL Tone when I was a kid. I still had it years later when I started recording and used it a couple of times, but it was in bits by then and powered by a couple loose wires connected to a battery pack. A few years ago I saw one in a charity shop and my then girlfriend bought it for me as a gift. Then we split up and she took it with her. How I miss her now - the VL Tone not the girlfriend!
