Pedals that stack with the Maxon OOD-9

ThorpyFX The Dane

Put ThorpyFX The Dane in front and the mid-forward tone leans further toward fuzzy

Black Arts Toneworks LSTR Fuzz

Run mid-forward into Black Arts Toneworks LSTR Fuzz for more fuzzy on top

Fuzzrocious Cosmic Bull Shark

Keep Fuzzrocious Cosmic Bull Shark after Maxon OOD-9 in the signal chain, clear of Maxon OOD-9's own gain stage

Artec SE-NGT

Run the SE-NGT ahead of the OOD-9 to gate out hiss before the consistent, mid-boosted TS-voiced drive reacts.

Red Witch Titan

Keep Maxon OOD-9's mid-forward voice out front: Red Witch Titan goes after Maxon OOD-9 in the signal chain so its ambient voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

EarthQuaker Devices Afterneath

Put EarthQuaker Devices Afterneath after Maxon OOD-9 in the signal chain, clear of Maxon OOD-9's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
