Description

If you know your British, 80s, kid’s TV shows then you might remember that Kevin the Gerbil was the best mate of Roland the Rat – any guesses what famous distortion pedal this one’s based on?

That’s right – the classic RAT!

Designed to fit neatly in a 1590B enclosure, and with easy-to find onboard pots (1x 16mm and 2x 9MM), this pedal will never leave your board.
