Abstract
A system is provided for use with an electrical musical instrument for conditioning electrical signals generated by the instrument. The system includes an amplifier circuit having an input for responding to the signals and an output to provide a conditioned output signal. At least one compressor is operatively connected to the input for responding to the amplitude of the signals to provide a compressed signal to the amplifier circuit that is variable as a nonlinear function of the amplitude. Also provided are a pair of bandpass filters in parallel for frequency preemphasis of the compressed signal. Also provided is time modulation circuitry for permitted certain musical sound effects.
