The Analog Fox Green Muff Fuzz Distortion is a fuzz/distortion pedal based on the Sovtek Russian Big Muff, the Russian-built branch of the Big Muff family. Pedal of the Day's review describes it as keeping "the same simple control setup and killer tonality as the origin," with the sound "darker, more distorted and full of sustain" than a straight clean signal1. If you know the Electro-Harmonix Green Russian Big Muff, you know the territory: the Sovtek design is a fuzz/distortion pedal in the Big Muff lineage2.
What it does
The pedal follows the classic three-knob Big Muff layout:
| Control | What it does |
|---|---|
| Volume | Adjusts your overall output |
| Tone | Acts as either a high or low-frequency cut |
| Distortion | Sets the amount of fuzz/distortion/sustain |
Circuit and components
Part of the appeal of the Russian Big Muffs is the specific parts used, and Analog Fox carries those over. The pedal uses "the same old stock transistors (kt3102em)" and "diodes (kd521a)" as the original design1. That component fidelity is what the reviewer tied to the pedal's tone: "the tones produced are right on point with the vintage units"1.
How it compares
The Green Muff sits in a family of Big Muff-style pedals. The Electro-Harmonix Green Russian Big Muff is the current production version of the Sovtek pedal the Analog Fox is based on2, and other makers have built on the same blueprint, such as the McCaffrey Audio Green Vodka Muff, a "transistor-based fuzz with symmetrical clipping"3. The Analog Fox distinguishes itself by using the original Russian transistor and diode types rather than modern substitutes1.
