ABSTRACT:
An apparatus to pick up and amplify sounds created by vibrations of a flexible member having a base which supports a sound pick up that transmits a signal to an amplifier. The apparatus is attached to the flexible member by an attachment assembly mounted on the base at an approximate center of gravity of the apparatus. The attachment assembly has two points of attachment such that when the flexible member is under tension a rotational force around the attachment assembly brings the sound pick up close to or in contact with the flexible member. The apparatus may also have the sound pick up mounted to a speaker that is mounted to the base. The apparatus may also have the sound pick up mounted to the base and transmit a signal to a separate amplifier.
