Pedals that stack with the T-Rex DR. Swamp

MXR Micro Amp

Run fuzzy into MXR Micro Amp for more clean boost on top

JHS Colour Box V2

Put JHS Colour Box V2 in front and the fuzzy tone leans further toward clean boost

Cordovox PH-8

Put Cordovox PH-8 after T-Rex DR. Swamp in the signal chain, clear of T-Rex DR. Swamp's own gain stage

Jackson Audio Bloom EQ Boost Compression

Jackson Audio Bloom EQ Boost Compression's own transparent character is the real reason this is worth trying

Electro-Harmonix Canyon

Keep T-Rex DR. Swamp's saturated voice out front: Electro-Harmonix Canyon goes after T-Rex DR. Swamp in the signal chain so its modulated voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Melee Wall of Noise Black

Run Walrus Audio Melee Wall of Noise Black after T-Rex DR. Swamp in the signal chain, clear of T-Rex DR. Swamp's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
