The Electro-Harmonix Flatiron Fuzz is a classic op amp powered fuzz and distortion based on the hard clipping op amp circuit famously associated with early ProCo Rat and op amp Big Muff style tones. It has three controls, Volume for output, Drive for sustain and distortion, and a Filter that acts as a movable low pass cutoff to shape brightness. At lower drive it stays fairly clean with a pleasing mild distortion, while higher settings deliver thick, meaty, aggressive fuzz distortion. Compact and straightforward, it suits rock, punk, alternative and garage players who want a versatile op amp fuzz distortion ranging from light grit to thick, cutting saturation with flexible tone shaping.
The Electro-Harmonix Green Russian Big Muff is a faithful reissue of the 1990s Sovtek-era Russian Big Muff, delivering a thick, creamy, bass-heavy fuzz with a darker, grittier character than other Muffs. Its low end is huge while the upper mids stay prominent but slightly scooped, and the distortion has a coarse, percolating texture with smooth sustain. Reviewers find it a near dead-ringer for an original Sovtek unit, dynamic and capable of passing a blind comparison. The beefy low end and dark voicing make it a favorite for grunge, stoner rock, doom, and heavy riffing, where its wall-of-fuzz thickness and sustain shine. With Volume, Tone, and Sustain controls it ranges from gritty rhythm crunch to saturated leads, sitting tonally as the bassiest, darkest member of the Big Muff family.
