Pedals that stack with the MXR Phase 90

Cornerstone Colosseum

Run the Phase 90's classic sweep after the Colosseum's harmonic, versatile gain and the modulation has real body to color.

Meris LVX Delay

Put the Phase 90 ahead of the LVX's delay repeats so the modulation gets echoed cleanly instead of smearing into the trails. — goes in the amp's FX loop (or last, into a clean amp)

Crazy Tube Circuits Splash

Run the Phase 90's classic sweep after the Splash's shimmering, surf-voiced reverb and the modulation colors the reverb tail directly. — goes in the amp's FX loop (or last, into a clean amp)

Source Audio Nemesis

Run the Phase 90 before the Nemesis so its classic sweep becomes part of what the delay repeats. — goes in the amp's FX loop (or last, into a clean amp)

Zevex Zvex Distortron

The Distortron's thick, harmonic distortion gives the Phase 90's organic sweep an aggressive signal to work across.

Catalinbread Dirty Little Secret MKI

Run the Phase 90's classic sweep after the DLS MKI's dynamic, bluesy lead crunch and the modulation has real body to color.

Voodoo Lab Proctavia

Layer the Phase 90's organic sweep after the Proctavia's thick, classic octave fuzz for psychedelic movement on an already-strange signal.

DOD 250 Overdrive Preamp 50th Anniversary

Run the Phase 90's classic sweep after the DOD 250's touch-responsive JFET drive and the modulation has real body to color.

JHS Pedals JHS Kilt V3

Phase 90's classic swirl colors the Kilt V3's British-voiced distortion after the gain rather than adding to it.

Hiwatt WEM Copicat Boost

Phase 90's psychedelic swirl colors the Copicat Boost's clean signal after the gain rather than adding to it.

Universal Audio OX Amp Top Box

Keep Universal Audio OX Amp Top Box's dynamic voice out front: MXR Phase 90 goes after Universal Audio OX Amp Top Box in the signal chain so its fuzzy voice doesn't muddy it

Wampler Sovereign Distortion

The Sovereign's rich, stage-ready distortion gives the Phase 90's organic sweep a thicker signal to sweep across.

Wampler Pinnacle Standard V2

Layer the Phase 90's organic sweep after the Pinnacle's sustained, hard-rock distortion for texture on an already-thick signal.

Old Blood Noise Endeavors Excess

Excess's own modulation and filter options layer differently-shaped sweeps under the Phase 90 if stacked, for a thicker, more experimental wobble.

Tech 21 GED-2112 Bass

Add the Phase 90's organic sweep on top of the GED-2112's own DI'd bass drive for movement without recoloring the low end.

Electronic Audio Experiments Eldritch Blast V3

Run the Phase 90's classic sweep after the Eldritch Blast's glitchy sub-octave fuzz so the modulation rides clearly on top of that electronic texture.

ThorpyFX Fallout Cloud

Layer the Phase 90's organic sweep after the Fallout Cloud's boutique silicon fuzz for classic-rock movement on an already-textured signal.
