Caterwauling guitar

A caterwauling guitar is a type of guitar created by Sloppy Smurf in the EMPATH: The Luckiest Smurf story series. It is analogous to the human musical instrument called the electric guitar, in that it can create distorted guitar sounds that can be described as squealing or growling, depending on what kind of notes are being played. Sloppy was inspired to create this when he heard Azrael's squealing when he got on the bad side of his master Gargamel's temper, noting how musical the squealing had sounded to him.
