Pedals that stack with the ProCo RAT 2

Crazy Tube Circuits Cyclone

Run the RAT2's gritty, low-gain distortion ahead of the Cyclone so the modulation swirls over an already-saturated tone instead of a clean one.

Hungry Robot The Borderland

The RAT's dark, cutting distortion is a rawer gain than the Borderland's own lush, boutique ambient reverb offers on its own. — goes in the amp's FX loop (or last, into a clean amp)

Hungry Robot Moby Dick V2

The RAT's dark, cutting distortion is a rawer gain than the Moby Dick's own massive, lush reverb texture offers on its own. — goes in the amp's FX loop (or last, into a clean amp)

Pigtronix Echolution

The RAT's dark, cutting distortion gives the Echolution's own complex, boutique delay something real to bite into before the repeats. — goes in the amp's FX loop (or last, into a clean amp)

EarthQuaker Devices Spatial Delivery V3

Run the RAT's dark, cutting distortion before the Spatial Delivery so the envelope filter has real gain and edge to track.

Pigtronix Philosopher King

Ahead of the RAT's cutting distortion, the Philosopher King's boutique compression evens out pick attack before the clipping stage adds its own grit.

Walrus Audio Fathom

The RAT's dark, cutting distortion gives the Fathom's own ambient, studio-grade reverb a real gain stage to trail behind rather than just space. — goes in the amp's FX loop (or last, into a clean amp)

Ibanez Soundtank CS5 Super Chorus

The RAT's dark, cutting distortion is a rawer gain than the CS5's own rich, analog chorus modulation offers on its own.

Meris LVX Delay

The RAT's dark, cutting distortion is a rawer gain than the LVX's own ambient, MIDI-controllable delay offers on its own. — goes in the amp's FX loop (or last, into a clean amp)

W-LM Compression Fracture

Run the RAT's dark, cutting distortion after the Fracture's own boutique, dynamic compression for a sharper front end going into the gain.

EarthQuaker Devices Spatial Delivery V2

Push the Spatial Delivery's glitchy, synth-voiced envelope filter with the RAT 2's bright, cutting distortion and the two textures compound into real dirt.

Crazy Tube Circuits Splash

The RAT 2's bright, cutting distortion gives the Splash's shimmering, surf-voiced reverb a driven signal to trail off, not real gain to stack. — goes in the amp's FX loop (or last, into a clean amp)

Source Audio Nemesis

The RAT's dark, cutting distortion gives the Nemesis's own digital delay platform a real gain stage to sit behind rather than more repeats. — goes in the amp's FX loop (or last, into a clean amp)
