Pedals that stack with the Aria Lil' RAT Distortion

Electro-Harmonix Green Russian Big Muff

The Green Russian's smooth, sustaining Muff fuzz gives the Lil' RAT's analog clipping somewhere heavier to land.

Dunlop MXR Distortion Plus

The Distortion Plus's warm, compressed clipping stacks with the Lil' RAT's own analog clipping for two distinct gain stages.

Hughes & Kettner Tube Rotosphere MKII The Analog Leslie Simulator

Run the Rotosphere's Leslie-style swirl after the Lil' RAT's own analog clipping settles, so the modulation moves a defined tone.

Ashdown Velvet Compressor

Run the Velvet Compressor ahead of the Lil' RAT for even attack and decay before the analog clipping reacts.

Caroline Guitar Company Kilobyte

Keep the Kilobyte's digital echoes trailing after the Lil' RAT's analog clipping, not before, or the delay repeats an unshaped signal. — goes in the amp's FX loop (or last, into a clean amp)

Dunlop - MXR Carbon Copy Deluxe Analog Delay

Run the Carbon Copy Deluxe's warm analog delay after the Lil' RAT's clipping settles, so the repeats trail a defined tone. — goes in the amp's FX loop (or last, into a clean amp)
