Pedals that stack with the Subdecay Super Spring Theory Reverb

Electro-Harmonix Green Russian Big Muff

Electro-Harmonix Green Russian Big Muff's own smooth character is the real reason this is worth trying

Electro-Harmonix Small Stone

Keep Subdecay Super Spring Theory Reverb's spring voice out front: Electro-Harmonix Small Stone goes after Subdecay Super Spring Theory Reverb in the signal chain so its analog warmth voice doesn't muddy it

ZVEX Fuzz Factory

ZVEX Fuzz Factory leans toward fuzzy, and that's a real, usable character to pair with

Walrus Audio Julia

Put Walrus Audio Julia after Subdecay Super Spring Theory Reverb in the signal chain, clear of Subdecay Super Spring Theory Reverb's own gain stage
