His goal is that to transfer the string vibartion to the phongraph.  So he create 6 small circle of the horseshoe magnets for each string of the guitar. he succeed with his prototype to tranfer the vibration of the stringGeorge called his friend Harry Watson that skilled with crafting something. He called him to create the wooden neck and the body for the elctric guitar. After spend many hours the shape of the guitar already formed and called as "Frying Pan." Putting all the thing together between the body and the prototype the electric guitar was born.
