Various manufacturers attempted to reproduce the sound of church organs on electronic instruments. In 1955, the Ahlborn & Steinbach company built its C1 model, the first electric organ in Germany with single-tone production. It followed the example of American models. The instrument had one manual. Three different timbres (organ, reeds, strings) were set using toggle switches, and seven pedal registers could be selected. The independent generators produced distinct single tones and a great volume of sound.
