A connector device for electronic musical instruments. The connector device comprising input electrical connector means that receives electrical signals generated by pickup means for an instrument. The instrument being played and a vibration transducer mechanically attached to the input electrical connector means or provided as an integral part of the input electrical connector means, such that vibrations from the instrument are transferred to the vibration transducer. The vibration transducer generates an electrical output signal based on the vibrations. The connector device comprises electrical output connector means that receives the electrical signals generated by the pickup means and the electrical output signal from the vibration transducer and provides these signals to equipment. The connector device further comprises a mixer that combines the signals vg(t) from the pickup means and the signal vvib(t) from the vibration transducer. The mixer provides output signal vo(t) that is a weighted combination of the input signals.
