Flavio Sosa's guitar is like no other. Combining a regular electric guitar, an iPhone (used as a synthesizer), and a theremin into a single instrument is no small feat! Flavio calls the instrument the "Theramine". According to Flavio, it's the first in the world of its kind and the second featuring a theremin. The Theramine was created specifically for the song "My Theramine", shown in the video above.
