Abstract: An improved string musical instrument is disclosed wherein a dynamic tone engendering structure provides adjustable filtering and conditioning of each of the variously tuned string's vibrational behavior. Acoustic energy transmission paths are provided for the overtone and fundamental tone components produced by the variously tuned strings, assuring even transmission of each string's particular acoustical energy to acoustical summing nodes where transducers convert acoustical energy to electrical energy. The present invention closely emulates the characteristic dynamic response and musical timbres found in a wide variety of traditional acoustic instruments.
