Pedals that stack with the Demon FX Pearl White Auto Wah

Walrus Audio EB-10

Demon FX Pearl White Auto Wah leans toward dynamic, and that's a real, usable character to pair with

Xotic RC Booster

Xotic RC Booster's own transparent character is the real reason this is worth trying

Electro-Harmonix Canyon

Keep Demon FX Pearl White Auto Wah's dynamic voice out front: Electro-Harmonix Canyon goes after Demon FX Pearl White Auto Wah 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)

Empress Echosystem

Keep Empress Echosystem after Demon FX Pearl White Auto Wah in the signal chain, clear of Demon FX Pearl White Auto Wah's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
