The MAS Effects Wendigo Scrambler is an octave fuzz pedal based on the Ampeg Scrambler, with an added Volume circuit. MAS Effects describes the Scrambler design as "a really unique pedal, known for very musical and harmonic distortion."1
What it is
The Wendigo takes the Ampeg Scrambler circuit and adds a Volume circuit of MAS Effects' own. The maker's product page describes it simply: "This is an octave fuzz based on the Ampeg Scrambler, but with an added Volume circuit."2
The circuit it comes from
The Ampeg Scrambler is an octave-up fuzz pedal from 1968, as JHS Pedals notes in a buying guide on pedals that have crossed the thousand-dollar mark.4 Aion FX calls the original "an exceptionally rare octave-up fuzz pedal" and places it alongside a family of octave fuzzes that each reach the octave in their own way5:
| Circuit | What Aion FX says about it |
|---|---|
| Ampeg Scrambler | "an exceptionally rare octave-up fuzz pedal"5 |
| Superfuzz | in the same vein, but generates its octave with its own technique5 |
| fOXX Tone Machine | in the same vein, but generates its octave with its own technique5 |
| Octavia | in the same vein, but generates its octave with its own technique5 |
Because all four circuits use their own techniques to generate the octave, they all sound different.5
Reviewers have long treated that voice as the pedal's calling card. MusicRadar's review of the Scrambler SCP-OD found "a unique and sought after upper octave fuzz sound."6 A Premier Guitar reviewer wrote that "the Scrambler had a truly unique octave fuzz voice" and found a loyal cadre of devotees among the fuzz cult, aided by its rarity.7
"The Scrambler's huge upper-octave fuzz sound ran counter to the popular Big Muff-style fatter and thicker amp-like tone."
Writing for Delicious Audio, Blake Wright and Paolo De Gregorio also noted that "There are clones of the Scrambler around" from various builders.8
