ABSTRACT:
An electronic organ in which a manually adjustable potentiometer varies the control voltage supplied to a voltage controlled amplifier interposed between a source of tone signals and an organ output circuit with the potentiometer being connected to the amplifier by a circuit which eliminates scratching and discontinuity in the potentiometer output. The amplifier can be bypassed by circuitry for supplying lower frequency bass signals to the amplifier output under conditions of high attenuation of the incoming signal in the amplifier.
