The StoneFly Effects Two Headed Werewolf is a fuzz pedal with a built-in octave section, described by Pedal of the Day as "a fuzzy, octave-laden power box"1. It is a handmade pedal aimed at players who want both fuzz and octave sounds from one enclosure, with a reviewer's verdict that the two sections combine "to form an all-powerful effects pedal that is NOT to be toyed with"1.
Where it came from
Pedal of the Day describes the circuit as building off the classic Gary Hurst CBS Arbiter Doubler and the Foxx Tone Machine, both fuzz-with-octave designs1. StoneFly built it on a tag-board rather than a printed circuit board, adding a noise filter to the circuit for players using a bad power supply1. The enclosure carries "super-unique and intricate artwork" by Adrian Brouchy from Coven Illustracion1, part of what the reviewer calls StoneFly's "crazy array of graphics, enclosure sizes, control knob placement and more" that makes their pedals easily recognizable1.
The initial run was limited to just 25 units1.
Controls and footswitches
The pedal has three knobs and two footswitches, so the fuzz and octave sections can be switched independently1.
| Control | What it does |
|---|---|
| Sustain | Sets the amount of fuzz |
| Filter | Shapes the tone |
| Volume | Sets output level |
The Sustain, Filter and Volume controls, in Pedal of the Day's words, "let you determine how this beast is gonna punish your amp"1.
With the toggle up, the first footswitch is Fuzz On/Off and the second is Octave On/Off1. With the toggle down in the Germanium position, that feature is reversed1.
The Germanium toggle does more than reverse the footswitches: it switches the Q1 transistor for a Germanium Sanyo 2SD72, which Pedal of the Day says offers "a complete other flavor"1.
Transistors and sound
The Two Headed Werewolf is loaded with 4 Silicon BC 549 transistors, which the reviewer says provide "more fuzz and a more present octave section"1. Flipping the toggle swaps in the Germanium transistor for a different character1. Pedal of the Day's overall read was that the pedal offers "a huge range of both fuzz and octave sounds, and plenty of options for any hard rock/doom/stoner rocker"1.

Questions
What circuits is the StoneFly Two Headed Werewolf based on?
Pedal of the Day describes the Two Headed Werewolf as building off the classic Gary Hurst CBS Arbiter Doubler and the Foxx Tone Machine, two fuzz-with-octave designs. StoneFly built the circuit on a tag-board and added a noise filter for players using a noisy power supply.
What does the Germanium toggle do on the Two Headed Werewolf?
The toggle switches the Q1 transistor for a Germanium Sanyo 2SD72, which Pedal of the Day says offers a complete other flavor. With the toggle down in the Germanium position, the footswitch feature is reversed, so the first footswitch no longer controls the fuzz and the second no longer controls the octave.
Does the Two Headed Werewolf take a battery?
Yes. Pedal of the Day notes the pedal features a battery door for easy, convenient battery replacement, so you can swap the battery without opening the enclosure.
How many Two Headed Werewolf pedals were in the first run?
The initial run was limited to just 25 units, according to Pedal of the Day's 2016 review.
Can I use the fuzz and the octave separately?
Yes. With the toggle up, the first footswitch is Fuzz On/Off and the second is Octave On/Off, so each section can be switched independently. With the toggle in the Germanium position (down), that footswitch feature is reversed.
