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 Maxon SD-9 Sonic Distortion is an iconic vintage Japanese distortion pedal from Maxon, known for its unique, raw, and slightly acidic distortion character that crosses the line between distortion and fuzz. The SD-9 was used by Kurt Cobain of Nirvana as his primary distortion pedal, and its distinctive, slightly ragged harmonic character became associated with the Nevermind-era grunge sound. The circuit produces aggressive, cutting, raw distortion with a character that no other distortion fully replicates.
