Abstract
A system is provided for use with an electrical musical instrument for conditioning electrical signals generated by the instrument and for creating controlled distortion. The system includes an amplifier circuit having an input for responding to the signals and an output to provide a conditioned output signal. There is included at least one bandpass filter for frequency preemphasis of the input signal. A limiting circuit is operatively connected to the bandpass filters limiting the amplitude of signals received from the bandpass filters to produce a relatively high distorted, long sustained signal. A notch filter operatively connected to the limiting circuit reduces the heavy mid-range frequency content produced by the combination of the bandpass filters and the limiting circuit. A low pass filter operatively connected to the notch filter further conditions the signal generating a conditioned output signal.
