Pedals that stack with the Tech 21 SansAmp Character Plus English Muffy

Univox Uni-Vibe

Catalinbread Giygas

Put Catalinbread Giygas in front and the fuzzy tone leans further toward octave

JHS Colour Box V2

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

Pigtronix Echolution

Keep Pigtronix Echolution after Tech 21 SansAmp Character Plus English Muffy in the signal chain, clear of Tech 21 SansAmp Character Plus English Muffy's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Melee Wall of Noise Black

Keep Tech 21 SansAmp Character Plus English Muffy's analog warmth voice out front: Walrus Audio Melee Wall of Noise Black goes after Tech 21 SansAmp Character Plus English Muffy 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)
