Abstract
Abstract An electronic organ in which all of the tones generated are applied through an artificial reverberation unit to the output speakers. The reverberation unit includes a pair of coiled springs with a coupling section between two portions of each spring. The reverberation or decay time is varied by an adhesively coated wire which is controllably brought just to rest on the coupling section so as to adhesively grasp the section. Since all of the signal is passed through the springs, the tone generators may be designed to compensate for both the poor frequency and the poor tonal characteristics of the springs, whereby exceedingly low frequency tones can be transmitted through the reverberation unit and have their reverberation time controlled and the metallic sound usually associated with reverberation units obviated.
