Abstract: A thumb mounted striking device is for use on stringed musical instruments, particularly electric bass guitars, whereby the striking mechanism is attached to and rendered integral with said ring element which is placed upon the thumb. The striking mechanism projects outwardly and is nominally flat, with the planar striking surface having an axis parallel to the axis of the thumb and an axis tangential to and normal to the axis of the thumb. Its attachment to the ring element is at the outward portion of the ring when said ring is placed upon the thumb.
