  • Patent number: 6127613
    Abstract: A pick assembly for use in plucking or strumming the strings of a stringed musical instrument is provided with a relatively inflexible plectrum element and a relatively flexible and short molded tether body element bonded at one end to the plectrum element and having a finger loop at the other end. A preferred tether body element cross-section, in combination with friction engagement of the pick assembly with the user's forefinger, significantly restricts rotation of the assembly about the axis of the user's forefinger.
