Pedals that stack with the Electro-Harmonix Good Vibes

Z.Vex Super Hard On

Run fuzzy into Z.Vex Super Hard On for more clean boost on top

Aguilar Octamizer (Bass Octaver)

Put Aguilar Octamizer (Bass Octaver) in front and the fuzzy tone leans further toward octave

Electro-Harmonix Stereo Memory Man Vintage

Keep Electro-Harmonix Good Vibes's smooth voice out front: Electro-Harmonix Stereo Memory Man Vintage goes after Electro-Harmonix Good Vibes 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)

Pigtronix Echolution

Pigtronix Echolution's modulated voice goes after Electro-Harmonix Good Vibes in the signal chain — it's not there to compete with Electro-Harmonix Good Vibes's own smooth character — goes in the amp's FX loop (or last, into a clean amp)
