Update via Aud1073cH in the comments: "I've got one of these- Sharper Image has their name on it, but it was made by Vocolo. The same people that brought us the Vocalizer 1000. (Just search for Captain Kazoo on YouTube.)"
Update via john in the comments: "No - not made by the same people that made the Vocalizer. I know, because I am one of the inventors! :-)"
"This wonderful device was exclusive to the Sharper Image stores and quite costly for the times. It was marketed as a way for someone to make their own music, without learning to play a keyboard, or even knowing how to sing very well. It takes voice input and converts the vocal sounds to Musical Instrument Digital Interface (MIDI) signals or digital codes. Use it just for fun, or in a more sophisticated manner if you possess musical talent... The operating manual, in pdf format, is available online to print or save to your computer at:
You can also go to the YouTube link listed below [above] to see Captain Kazoo demonstrate the use of the Breakaway Vocalizer 1000. He has four or five other links, on the same site, where you can listen to several recordings he made using this same synthesizer."
