Out of all the variations of the ProCo RAT distortion, William Benton easily crowns the Vintage RAT as the RAT King. This flexible pedal (he used it on bass in his former punk band, uses it on guitar for Lucky Pineapple and uses its filter functions when other distortions are engaged) is not to be confused with the Rat King, the sewer-dwelling TMNT villain who wore moth-eaten clothes and rags over his face -- that's a lot of unnecessarily planned costume-work for someone aiming to appear naturally vagrant.
