Patent
In the guitar circle, Petillo is most famous as the inventor of the "Petillo Precision Fret." In a patent filed on June 22, 1976, the new fret was described as "a substantially T-shaped fret for a stringed instrument which has an elongated stem topped by a triangularly shaped cap." Petillo's triangular frets result in more precise intonation; however, not all guitarists are comfortable with their rigid feel. The Revolutionary Drumstick Patent of Petillo was sold to Ambico at the NAMM Convention in GA, 1977
