Pirro is the inventor of the Copperphone, a hand crafted microphone designed and built through his company Placid Audio. The Copperphone uses components from vintage communications equipment as well as a mechanical filtering device to achieve a limited bandwidth frequency response similar to that of AM radio and the nostalgic sound of the early days of recording. He designed the first Copperphone while playing with The Polyphonic Spree, as a way to produce a "telephone" voice effect for lead singer DeLeaughter. The Copperphone has been used by many artists, including Green Day, Queens of the Stone Age, Lou Barlow, Rush, Norah Jones, Jack White, St. Vincent, as well as Grammy Winning producer Jacquire King.
