Pedals that stack with the Electro-Harmonix Q-Tron Plus

Fjord Fuzz Odin

The Q-Tron's dynamic envelope-filter sweep colors the signal feeding the Odin's heavy doom fuzz stage.

ThorpyFX The Dane

Push the Q-Tron's filter with the Dane's dynamic, harmonically complex drive first, so the quack tracks a hotter signal instead of a bare guitar line.

Dawner Prince Boonar

The Q-Tron's dynamic envelope-filter sweep colors the signal before the Boonar's Echorec-style repeats echo it. — goes in the amp's FX loop (or last, into a clean amp)

Electro-Harmonix XO Deluxe Memory Man

Keep the Memory Man's echoes after the Q-Tron's envelope sweep, so the filter tracks a dry signal instead of chasing repeats. — goes in the amp's FX loop (or last, into a clean amp)
