Octavia (effects pedal)

The Octavia is an effects pedal made by Roger Mayer. First produced in 1967, early versions of the unit doubled the input signal from an electric guitar one octave higher in pitch. Jimi Hendrix popularized the Octavia, combining it with fuzz distortion pedals on songs like "Purple Haze", with later versions incorporating octave and fuzz effects into a single enclosure. As Mayer did not initially release the Octavia commercially, several companies began producing similar pedals in the 1970s, and octave-fuzz went on to become a common style of effect.
