Product Description

The Hephaestus started life as a simple take on the classic Jordan Boss Tone circuit. That little plastic box you plugged directing into your guitar to get that classic “Spirit in the Sky” fuzz sound. By adjusting the voltage to the circuit itself you get a very sporadic octave down effect, essential turning that little plastic fuzz box into the antioctavia.

The Hephaestus features a single external “Warning” knob that adjusts voltage of the unit. When the warning knob is set to maximum (fully clockwise) you get classic fuzz tones but once you hit 1 o’clock, the suboctave effect starts to happen. Continuing to turn the “Warning” knob down makes that octave effect more prevalent. It’s weird, unpredictable, but most importantly it’s incredibly musical. There are riffs to be found in the Hephaestus!

Internally there is a master volume so you can adjust the overall output of the pedal. The Hephaestus comes in a mini size format, features a single external “Warning” control, and has an internal volume trimmer for output level adjustment.

Key Features

  • Warning Knob - The Warning knob on the face of the pedal does not control volume, it doesn’t control gain, it controls voltage feeding the circuit! When maxed out the circuit sounds like the best of the classic circuit, but as you turn the knob down, you adjust the overall voltage entering the circuit. Once the knob hits 1 o’clock something magical happens, a sub octave begins to be introduced! When and where it appears will be very dependent on your guitar and amp setup but it creates a sub octave synth effect you’re sure to love! Further reducing the voltage or WARNING knob will cause even more octave things to happen while reducing the overall gain of the circuit.


  • Warning Dial: Controls the voltage feeding the circuit.
  • Bypass: True Bypass
  • Size: Mini
  • Power: 9V DC Adapter (Not included)
