This violin makers shop by W. Foster Tracy, is a miniature built inside a full-size violin. It was on display at the Mini Time Machine Museum of Miniatures, Tucson, Arizona. All completed instruments and tools are fully functional in this model.
Brussels- Musical Instruments Museum Appears to be a combination harp/piano, or a way of opening it up to get the string tones out more? Maybe one person plays the harp while the other plays the piano ON ONE INSTRUMENT!
I realize it's not a guitar.but this is one bad electric violin! ever since i found out these exsisted i wanted one, because i heard you could plug them into headphones and learn to play without bothering everyone.
