Pedals that stack with the Catalinbread Callisto MkII All-Analog Chorus

Ibanez Tube Screamer

Run the Tube Screamer into the Callisto, not the other way, so the chorus doesn't get chewed up by the drive's added gain.

Wren and Cuff Box of War Small Foot Fuzz

Run the Box of War's searing fuzz into the Callisto and the chorus keeps that sustained wall of gain from turning into mud.

Put Catalinbread Callisto MkII All-Analog Chorus after Electro-Harmonix Satisfaction Plus Fuzz in the signal chain, clear of Electro-Harmonix Satisfaction Plus Fuzz's own gain stage

Keep Catalinbread Callisto MkII All-Analog Chorus after Fairfield Circuitry 900 Fuzz in the signal chain, clear of Fairfield Circuitry 900 Fuzz's own gain stage

Dawner Prince Boonar

The Boonar's vintage studio delay trails the Callisto's analog chorus-vibrato with a colored signal to echo. — goes in the amp's FX loop (or last, into a clean amp)

Catalinbread Fuzzrite Germanium

Keep Catalinbread Fuzzrite Germanium's germanium voice out front: Catalinbread Callisto MkII All-Analog Chorus goes after Catalinbread Fuzzrite Germanium in the signal chain so its modulated voice doesn't muddy it

Alexander Pedals SpaceXpander

Run the Callisto's analog chorus into the SpaceXpander and the modulation gets a spring-reverb tail instead of drying out at the end of the chain. — goes in the amp's FX loop (or last, into a clean amp)
