DigiTech Wah-ocTo-Fuzz

The DigiTech Wah-ocTo-Fuzz is a 3-in-1 effects pedal that combines wah, octave and fuzz in a single treadle-operated enclosure. It is a collaboration between two pedal names with long histories of their own: DOD and Morley. DigiTech's product page describes it as a case where "DOD and Morley have achieved" something together, harmonizing "Wah, Octave, and Fuzz perfectly encapsulated" in one pedal¹. Each effect can run on its own, or you can stack one, two, or all three at once, which opens up combinations from a plain wah to a full octave-fuzz-wah stack².

The pedal is aimed at more than one kind of player. Guitar.com's Crystal Koe reported that it is "designed for guitarists, bassists and keyboard players alike," with each effect runnable individually or all three stacked together³.

What it does to your sound

The octave section is where the pedal's pedigree shows most clearly. DigiTech says that "beneath its surface lurks the DOD FX35 Octoplus," a classic analog octave circuit. Premier Guitar's report on the release describes the octave section as using that FX35 Octoplus circuit to produce "a classic analog octave blend that channels the captivating, glitchy essence" of the 1980s octave section⁵¹. In plain terms, it is the sub-octave character of an analog octave pedal of that era, including the tracking quirks players associate with it. For more on that effect family, see Octave & Pitch Pedals.

The wah and fuzz sides draw on Morley's Power Wah and Power Fuzz, according to DigiTech's product page¹. The fuzz side gets its own level control, and the whole pedal carries a Morley buffer: Bass Magazine's report describes "a premium Morley buffer circuit designed to protect your tone from any mischief in your signal chain"². A buffer, for anyone new to the term, is a circuit that keeps your guitar's signal strong over long cable runs and crowded pedalboards; there is more on the type at Buffer Pedals.

Controls and how it is laid out

The pedal is operated with two footswitches and a rocker treadle. DigiTech's page lists an OCTAVE footswitch and a FUZZ footswitch alongside the treadle for the wah, with a red LED indicator that turns on when the OCTAVE footswitch is engaged¹.

The Fuzz Level knob is worth a second look: Bass Magazine describes it as managing "your overall signal when the fuzz is activated," meaning it sets level with the fuzz in play rather than only the fuzz's own volume². Guitar World's report describes the same dial as "for managing the wider signal"⁶.

On the back, the OUTPUT jack connects "to the input of another pedal or the input of your guitar amp," per DigiTech's product page¹.

Hardware details

MusicRadar's Jonathan Horsley noted that "the Wah-ocTo-Fuzz is equipped with a treadle with glow-in-the-dark grip tape," a practical touch for dark stages⁴.

Where it came from

The Wah-ocTo-Fuzz is played with two footswitches and the treadle: an OCTAVE footswitch and a FUZZ footswitch, with the treadle controlling the wah. A red LED indicator turns on when the OCTAVE footswitch is engaged¹.

What reviewers said

The pedal's two footswitches and treadle give a player several ways to use it: the OCTAVE footswitch and FUZZ footswitch can each be engaged on their own, with the red LED showing when the octave is on, and the treadle working the wah¹. Its output connects to the input of another pedal or straight to the input of a guitar amp¹.
