Much like a "Capo" or a "Slide", the Jellifish guitar pick is a mechanical device that is used on your guitar (or any other stringed instrument) to create new and unique sounds. The Jellifish looks similar, and is used in the same manner as a conventional guitar pick, but by no means is meant to replace it. It merely provides a new experience of playing your 6 string electric or acoustic, by creating 3 different sounds.
