ABSTRACT:
A system is provided for use with an electrical musical instrument for conditioning electrical signals generated by said instrument. Said system comprises an amplifier circuit having input means for responding to said signals and output means for providing a conditioned output signal, and at least one compressing means operatively connected to said input means for responding to the amplitude of said electrical signals to provide a compressed signal to said amplifier circuit that is variable as a nonlinear function of said amplitude.
