Zvex Jonny Octave
Zvex · pedal
The Zvex Jonny Octave is a clean analog octave-up pedal from Z.Vex Effects (Minneapolis, Minnesota), designed to raise single-note solos one or two octaves above the original pitch using four germanium diodes and a transformer in each channel. Four internal gain trimmers allow calibration for individual playing style. It produces the most transparent, natural-sounding octave-up effect when played on the neck pickup above the 12th fret.
