The R.A.T is a versatile guitar effect pedal based on the Pro Co Rat. It features 4 pots and a 3-way toggle for control. The pots adjust the volume, filter, distortion, and sweep. The sweep pot is a useful addition that allows for adjusting the clipping frequencies within the gain stage of the circuit, resulting in a darker tone as it is turned up. The three-way toggle switch allows for selecting between different diodes – stock silicon, LED (turbo), and asymmetrical.
