Pedals that stack with the Electro-Harmonix Bad

MXR M294 Sugar Drive Mini

Keep Electro-Harmonix Bad after MXR M294 Sugar Drive Mini in the signal chain, clear of MXR M294 Sugar Drive Mini's own gain stage

Line 6 DL4 MkII

Keep Line 6 DL4 MkII's analog warmth voice out front: Electro-Harmonix Bad goes after Line 6 DL4 MkII in the signal chain so its low gain voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

Ampeg Classic Analog Bass Preamp

Run Bad's subtle, resonant phase sweep after the Classic Analog Bass Preamp's own mid-forward EQ settles, so the modulation moves a defined tone.

Behringer BOD400 Bass Overdrive

Keep Electro-Harmonix Bad after Behringer BOD400 Bass Overdrive in the signal chain, clear of Behringer BOD400 Bass Overdrive's own gain stage

EarthQuaker Devices Astral Destiny

Electro-Harmonix Bad's low gain voice goes after EarthQuaker Devices Astral Destiny in the signal chain — it's not there to compete with EarthQuaker Devices Astral Destiny's own octave character — goes in the amp's FX loop (or last, into a clean amp)
