EMC

Electronics Music Corporation. Amplifiers and speaker cabinets previously produced in Cleveland, OH during the early 1970s.
The Electronics Music Corporation (EMC) produced solid-state amplifiers in Cleveland, OH during the early 1970s (catalogs exist from 1971 to 1973). They produced a wide range of guitar, bass, organ, and PA amplifiers. The configurations EMC used are very similar to Kustom of the same era (minus the cool Tuck 'N Roll covering). Most amps are piggybacks with separate heads and cabinets, but they did produce combo units as well.
