A sensor for detecting vibrations in a soundboard of an acoustic instrument, such as an acoustic guitar. The sensor includes a brace means mounted to the soundboard of the acoustic instrument. The sensor further includes a transducer mounted on the brace means. The brace means detects vibrations in a region of the soundboard in engagement with the brace means and transmits the detected vibrations to the transducer. The transducer subsequently generates an electrical output signal representing vibrations detected by the transducer. The brace means includes a plurality of brace members to which the transducer is mounted.
