Cut from a 12x18 sheet cake. Iced with buttercream. Decorations are made from mostly fondant. Knobs are molded white chocolate (from the lid of a tip case), the strings are spaghetti. Whammy bar is a long popsicle stick and the only inedible thing on the cake. Thanks to everyone on this site for all of their great pictures. I looked over them, got a lot of great ideas and then went to town with a picture of the guitar from the client.
