A vibration transmission adapter for the transmission of vibrations from strings of a string musical instrument to a sound reverberator device equipped with at least one spring is presented herein to enhance the sound generated by the instrument. The strings are supported in contact with a bridge saddle of the instrument. The vibration transmission adapter includes a rigid metallic member shaped to define a saddle connecting section and an integrally formed spring connecting section. The saddle connecting section is engageable into the bridge saddle and is shaped to extend between and spaced from at least two adjacent strings of a pair of strings. The spring connecting section extends in a rearward direction from a top end of the saddle connecting section and has a spring connecting free end.
