The Maestro FZ-1 Fuzz-Tone was the first fuzz distortion device to become widely available on the market for electric guitars and basses, although there had been other prototype devices made. It was designed by recording engineer Glenn Snoddy and WSM-TV engineer Revis V. Hobbs and manufactured by Gibson. Mr. Snoddy and Mr. Hobbs held U S Patent .# 3,213,181 issued October 19, 1965.

Maestro FZ-1 (along with its almost identical update the FZ-1a) achieved a peak of popularity in the 1960s. The device was used by Keith Richards in the Rolling Stones 1965 hit “Satisfaction” and became a favorite of many garage rock and psychedelic acts of the time. Gibson re-issued the FZ-1a in the 1990s, but later discontinued the model.
