From Gilmour to Grohl, the Pro Co Rat has earned its place as a bona fide classic distortion pedal since it was first released in 1978.

It’s been through many guises, too, including the Rat 2, You Dirty Rat and Vintage Big Box Rat reissue and many more. But now everyone’s favourite rodent-based dirt box has been given the miniaturisation treatment resulting in a ratlet measuring just 5cm wide by 8cm front to back and 5cm high.
