The Octavia is a fuzz which creates the octave doubling effect (one octave higher) made famous by Jimi Hendrix and Jeff Beck. The Voodoo Lab Proctavia is an exact replica of Tycobrahe Sound Company’s Octavia which was produced during the ‘70s. This was the model used by Stevie Ray Vaughan and considered the most desirable by vintage collectors. The Proctavia incorporates the same transistors, germanium diodes and unique transformer coupled output stage as the original circuit.


When you first try the Proctavia, if you merely plug it in and strum a chord, you will hear a dissonant distortion that sounds like it’s broken. You need to learn to play the Proctavia like a new instrument. It’s very sensitive to your guitar’s output level and harmonic content. You can control this with the guitar volume, how hard you play and your picking style. Here are some suggestions:

  1. Basic Octavia: Set the Boost all the way down and the Volume at about 1/2. Use the bridge pickup on your guitar. Back down your guitar volume a little. Play single notes at least half-way up the neck. You will get best results with new strings. Also, try hitting strings with the edge of your pick to emphasize harmonics.
  2. Super-long Sustain:Turn your guitar volume and the Boost all the way up. Set the Volume to the desired level. Play single notes for solos.

Plugging into the input jack turns on the power to your Proctavia. To preserve battery life, disconnect the input cable when not in use.


The Voodoo Lab Proctavia is powered by a single 9V battery. To replace the battery, remove the four screws which secure the bottom cover.

External Power

The Voodoo Lab Proctavia can be powered externally with a regulated 9VDC power supply eliminating the need for the internal battery. The external power supply connector is a standard 5.5×2.1mm barrel with center negative. Because the Proctavia is a positive ground circuit, it should only be used with a fully isolated power supply like the Voodoo Lab Pedal Power.
