The reviewer found the FATRAT useful for both guitarists and bassists who need a familiar distortion palette plus an option for smoother upper mids via the MOSFET clipping. Build and component accessibility also stand out thanks to the socketed op-amp for easy swapping and the pedal's US construction.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Clipping:\u003c\/strong\u003e Switch between the original RAT clipping and a new MOSFET circuit to choose between classic grit and a more amp-like, smoothed upper mid response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFAT Mode:\u003c\/strong\u003e The FAT selection increases bass response for a thicker tone, useful for bassists or guitarists who tune down for extended range styles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocketed Op-Amp:\u003c\/strong\u003e A socketed op-amp lets users change chips without soldering, enabling easy tonal experiments beyond the stock OP07DP.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUS Manufacturing:\u003c\/strong\u003e Built entirely in the United States, the pedal feels solid and consistent in quality compared with earlier RAT models.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Voltage Range:\u003c\/strong\u003e The pedal accepts nine to 18 volts DC, offering more headroom and the ability to dial in cleaner or more dynamic response.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe FATRAT is ideal for electric guitarists who like the classic RAT voice but want more tonal options, and for bass players seeking a distortion pedal with enhanced low end and the ability to retain definition.
