Welcome to the wacky world of analog octave—ZVex style!
The Jonny Octave is an octave-up effects pedal designed to raise the apparent pitch of single notes on your guitar by one or two octaves. Controls include volume controls for each of the two octave settings. Internal trim pots for gain stage control let you increase sustain or adjust the drive for your playing style.
Note: Due to the nature of each hand-painted Jonny Octave pedal, there may be a slight difference in design from the posted image.
