Abstract
A pickup unit of an electric stringed instrument is constituted of a vibrator supporting strings, a support which is installed inside the recess of a lower bridge so as to support the vibrator, and a plurality of piezoelectric elements which convert vibrations of strings transmitted thereto via the vibrator into electric signals. At least one presser member is interposed between the vibrator and the support. The presser member is constituted of a screw that is put into the lower surface of the vibrator from the lower surface of the support, thus upwardly pressing the piezoelectric elements onto the vibrator. This makes it possible to efficiently transmit vibrations of strings to the piezoelectric elements, thus improving the tone color and sound quality of an electric stringed instrument.
