Abstract
A signal processing circuit, for each string of a musical instrument which string is individually tuned to a frequency, includes a transducer adjacent to the string and an equalizer connected to an output circuit. To emulate an acoustic instrument, the equalizer is set to emphasize a signal present in a frequency range of the tuned frequency of the string and/or its harmonics. It also de-emphasizes at least low end frequencies below the operating range of the string. A mid-range frequency device is provided in the equalizer to produce characteristic mid-range response for a specific acoustic instrument. If the transducer produces an inherent resonance at a characteristic frequency, the equalizer will also de-emphasize the inherent resonance produced by the transducer at the characteristic frequency of the transducer.
