Pedals that stack with the DigiTech Whammy DT

Xotic RC Booster

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

Boss BD-2 Blues Driver

Maxon AD-9 Pro Analog Delay

Keep DigiTech Whammy DT's octave voice out front: Maxon AD-9 Pro Analog Delay goes after DigiTech Whammy DT in the signal chain so its analog warmth voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)
