Abstract
An apparatus and method for modeling an acoustic sound in an electric stringed musical instrument is provided. A preferred embodiment, among others, includes a bridge sensor configured to sensing string vibrations at the bridge of the instrument so that a bridge signal is generated in accordance with the vibrating strings. A body sensor, which may be positioned at different points on or within the body of the instrument, senses the resonance of the string vibrations. The body sensor generates a body resonance signal in accordance with the sensed resonance. An amplification circuit amplifies the body resonance signal when the amplitude of bridge signal exceeds a first predetermined level. In addition, a second amplification circuit amplifies the bridge signal. A summing circuit adds the amplified body resonance signal with the amplified bridge signal to produce an output signal that, when replicated in sound, models the sound of an acoustic instrument.
