Vivi-Tone was a musical instrument company founded in 1933 by Lloyd Loar, Lewis A. Williams, and Walter Moon in Kalamazoo. Lloyd Loar is best known for his innovative work with Gibson from 1919 to 1924 and he carried on this inventiveness with Vivitone. The company made electrified guitars, violins, mandolins, a keyboard, and at least one amplifier - but was ultimately not a commercial success.
