It used to be the octave fuzz effect (also known as the “Octavia,” designed by Roger Mayer) was that one buried pedal you’d break out and blow the dust off when you needed to cover Jimi Hendrix’s solos on Purple Haze and Who Knows

Not any more. Artists from Josh Homme to Kenny Wayne Shepherd have adopted some variation of an octave fuzz as part of their arsenal, not to mention an underground army of indie and alternative rock bands that continually use the octave fuzz to great effect (sorry). 

Cue newcomer Dusky Electronics from North Carolina, with their Augustus octave fuzz pedal to completely breathe new life into this “dusty” effect. 

Neither an “Octavia” clone nor a sub-octave fuzz, the Augustus is an original design that converts the incoming audio signal by “folding each wave in two to double its frequency.” This results in “severely mangling the waveform in the process,” according to the company. Now, I don’t know about you, but words like “folding” and “mangling” to describe an octave fuzz is something I want to explore immediately.

First off, the face of this octave pedal is emblazoned with a fearsome multi-tentacled octopus wearing a laurel wreath, which I’m assuming is a clever caricature of Caesar Augustus “Octavian” (I see what you did there, Dusky).

The solidly built Augustus features controls for Heat (amount of fuzz), Meat (bass content), Light (high-frequency content) and More (output volume). What’s neat is Meat and Light are subtractive EQ controls where it's best to roll them fully clockwise and work backwards to sculpt your preferred frequencies.

The pedal features a high-impedance input buffer, MOSFET input for increased response and dynamics, and can be run with a 9V battery or from a 9-18V power source (although Dusky notes that there’s no sonic benefit at 18V).

For the Augustus, it’s all about frequency content – where the interactive Meat and Light EQ controls offer surprising range for use as a thickening agent or subduing the overall shagginess to highlight the mids, which is why this musically textured pedal works great for stacking fuzzy octave timbres to just about any electronic instrument.

At 9 o’clock and up, the Heat knob dishes out piles of churlish distortion and turbulent sawtooth fuzz, and depending on how aggressively you pick or stab notes, the sputtering upper-octave ring-modulation effect always makes its presence known – even on cleaner settings.

For all its hirsute raucousness, the Augustus satisfyingly mangles its multilayered octave fuzz tones, and I’m thoroughly enchanted by this leviathan of a stompbox.
