The JOYO Voodoo Octave – JF-12 is a guitar effects pedal produced by JOYO Technology, a Chinese manufacturer of musical instrument accessories. The JF-12 Voodoo Octave is designed to recreate the classic octave fuzz sound popularized by the Octavia pedal used by legendary guitarist Jimi Hendrix.
The Voodoo Octave features controls for Volume, Tone, and Octave. The Volume control adjusts the overall output level of the pedal, while the Tone control allows you to shape the tonal characteristics of the effect. The Octave control blends in the octave-up effect, which adds an upper octave to your guitar signal, creating a unique and distinct sound.
