  • Patent number: 5515762
    Abstract: A guitar slide for permitting the user to contact a single string, or any pair of adjacent strings of a stringed instrument. The guitar slide includes a body of a length sufficient to contact any pair of adjacent strings on a stringed instrument, an inner end formed with a hole for receiving the tip of the user's finger, and an outer end formed with an arcuate end cap adapted to be positioned adjacent the tip of the user's finger. The guitar slide body is shorter than the distance between the tip of the user's finger and the first knuckle of the user's finger to assure that the finger has the same flexibility as if the user was not wearing the guitar slide, which length is sufficient to allow guitar slide 1 to contact any two adjacent strings.
