The switch to the “Small Box” RAT was essentially just a cosmetic makeover. While the circuit remained the same, the enclosure evolved into a more compact version, with a 12-gauge U-shaped base. The Pro Co logo sat next to the RAT logo on the pedal top, silk-screened in black inside of a white box. In 1986, the logo was reversed to white on the black, painted metal.
