Up for sale is the Electro-Harmonix Flatiron Fuzz. Named after the historic New York City landmark down the block from EHX headquarters, this pedal is a classic op-amp powered dirt box. Inspired by the legendary late-1970s "rodent" circuits (the ProCo RAT2), EHX engineered the Flatiron with symmetrical hard-clipping to deliver a sound that is arguably even meaner, punchier, and more articulate than the original. 

It is incredibly versatile: at lower drive settings, it functions like a gritty, touch-responsive overdrive. Crank the drive up, and it morphs into a thick, meaty, arena-rock fuzz that responds uniquely when you roll back your guitar's volume knob. 

Key Features

• Op-Amp Hard-Clipping Circuit: Delivers vintage '70s-era grit, sustain, and thick harmonic distortion.
• Unique Filter Control: A specialized low-pass filter with a movable cut-off frequency. Allows you to dial in your precise high-end response, moving easily from dark and woolly to raunchy and cutting.
• Dynamic Gain Range: Effortlessly transitions from a mild, bluesy grit to a wall-of-fuzz saturation.
• True Bypass Switching: Guarantees absolute signal path integrity, ensuring zero tone-suck when the pedal is disengaged.
• Compact Footprint: Pedalboard-friendly enclosure with standard 1/4" input and output jacks.
