Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

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 JHS x Electro-Harmonix Big Muff Pi 2 is a fuzz pedal built from a previously unproduced dual op-amp Big Muff schematic, discovered by JHS Pedals founder Josh Scott in the garage of a former Electro-Harmonix engineer and brought to market as a joint release between JHS and EHX. Its dual op-amp clipping gives a wider, less compressed low-mid response than classic triangle, civil-war or ram's head Big Muff variants, trading the airy midrange scoop of vintage Muffs for a brawnier, more physically imposing grind. It offers the same sustained, saturated Big Muff character but with less-refined, woolier clipping texture. A limited Big Box edition was released through JHS alongside a standard Nano version.
