Pedals that stack with the ProCo RAT 2

Ibanez Tube Screamer

Stacking the Screamer's mid-forward boost ahead of the RAT lets its own low-end roll-off tighten the signal before the RAT's Filter control reshapes it.

Jackson Audio Optimist

Run the Optimist ahead of the RAT and its natural JFET compression smooths out the RAT's cutting, bright low-gain drive.

MXR MC-402

Boost with the MC-402 first and the RAT's cutting low-gain drive gets pushed into fuller, more sustained saturation.

ZVEX Fuzz Factory

Stacking the RAT ahead of the unpredictable Fuzz Factory can tame its gating and noise into something more controllable.

Electronic Audio Experiments Surveyor V2.5

Stack the RAT2's gritty, low-gain distortion after the Surveyor's subtle, round drive for extra edge without losing that transformer-coupled warmth.

MXR Phase 90

Pairing the Phase 90 with the RAT is a documented combo — running the phaser after the distortion keeps its sweep defined rather than smeared by the gain. — also used together by 1 artist

Lovepedal Purple Plexi

Stack the RAT's cutting drive after the Purple Plexi for a two-stage push from natural breakup into tighter distortion.

EarthQuaker Devices White Light

Stack the RAT2's gritty, low-gain distortion after the White Light's bright, chimey boost for a grungier edge without losing that clarity.

Greer Mizuki blue

A RAT 2 stacked with the Mizuki Blue trades some of the overdrive's musical warmth for the RAT's brighter, cutting low-gain edge.

Wampler Cory Wong

Run the Cory Wong before the RAT to even out pick dynamics and add punch before the distortion's own filter clips it.

MXR Double Down

Stack the Double Down's transparent, consistent boost ahead of the RAT for more push into the distortion's clipping without adding its own flavor.

Mad Professor Simble Overdrive MK2

Stack the RAT's cutting drive after the Simble for a two-stage build from warm breakup into tighter distortion.

Death By Audio Moonbeam

Run the RAT2's gritty, low-gain distortion ahead of the Moonbeam so the stereo phasing swirls over an already-saturated tone.

Catalinbread Cloak

The RAT 2's bright, cutting distortion gives the Cloak's shimmering, harmonic 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)

Boss VB-2W

The RAT 2's bright, cutting distortion pushes on top of the VB-2W's liquid pitch-vibrato rather than genuinely stacking gain with it.

Electro-Harmonix XO Deluxe Memory Man

The Memory Man's lush analog echo trails smoothly behind the RAT's gritty distortion, its warmth softening the pedal's edge. — goes in the amp's FX loop (or last, into a clean amp)

Mooer woodverb

Put the woodverb after the RAT — the cutting distortion stays sharp and the reverb adds a warm, natural decay behind it. — goes in the amp's FX loop (or last, into a clean amp)

Wampler Sovereign Distortion

The RAT's dark, cutting distortion stacks with the Sovereign's own rich, stage-ready distortion for a sharper, brighter edge on top.

Wampler Pinnacle Standard V2

The RAT's dark, cutting distortion stacks with the Pinnacle's own sustained, hard-rock distortion for two distinct gain characters, not a wall of mush.

Old Blood Noise Endeavors Excess

The RAT's dark, cutting distortion stacks with the Excess's own experimental, filtered gain for something stranger than either pedal alone.

Tech 21 GED-2112 Bass

Stack the RAT's dark, cutting distortion after the GED-2112's own DI'd bass preamp for a sharper edge on the low end.

Electronic Audio Experiments Eldritch Blast V3

Stack the RAT2's gritty, low-gain distortion after the Eldritch Blast's glitchy sub-octave fuzz for a grungier layer on top of that electronic chaos.

ThorpyFX Fallout Cloud

Two gain stages for texture — the Fallout Cloud's harmonically rich silicon fuzz stacks ahead of the RAT's cutting distortion instead of doubling it.

Crazy Tube Circuits Splash MKIV Reverb

Run the RAT2's gritty distortion ahead of the Splash MKIV so the spring reverb tails a signal that's already saturated, not clean. — goes in the amp's FX loop (or last, into a clean amp)
