Nine different circuits

The OG mode offers the original 1979 version known as the 'Big Box' due to its large cabinet, while the WHT mode accurately recreates the sound of the subsequent 'Small Box' version with a white logo. Turbo mode is available for the extended dynamic range of LED-based clipping, while Brat mode provides the Input Buffer and additional Soft clipping for classic grunge sounds of the nineties. The famous Japanese version of the effect pedal is also represented with the LA mode. For additional sonic flexibility, the PackRat also features GRF, an extremely rare representative of the famous rodent, while fans of maximum distortion will find themselves in the PackRat's Dirty channel with maximum gain reserves and the highest saturation. Last but not least, the modern interpretations of the original are the JHS Mod and an additional circuit based on the Caroline Wave Cannon.
