Pedals that stack with the MXR Phase 90

Fender Blender

Layer the Phase 90's organic sweep after the Blender's dry octave fuzz for movement on an already-strange signal.

Benson Amps Stonk BOX

Layer the Phase 90's organic sweep after the Stonk BOX's raw germanium fuzz for movement on an already-gritty signal.

Walrus Audio Eras

Feed the Phase 90 with the Eras' heavy metal distortion and the sweep gets real teeth instead of staying polite.

Mooer A7 Ambience

Run the Phase 90 before the A7 so the phaser sweep gets wrapped in the ambient reverb's church-like tail. — goes in the amp's FX loop (or last, into a clean amp)

EarthQuaker Devices Dispatch Master V2

Run the Phase 90's classic sweep after the Dispatch Master's celebrated delay-reverb blend and the modulation colors the decay directly. — goes in the amp's FX loop (or last, into a clean amp)

Crazy Tube Circuits Echotopia

Run the Phase 90's classic sweep after the Echotopia's boutique tape echo and the modulation colors the repeats directly. — goes in the amp's FX loop (or last, into a clean amp)

Benson Amps Delay

Run the Phase 90's classic sweep after the Benson Delay's ambient slapback repeats and the modulation colors the echoes directly. — goes in the amp's FX loop (or last, into a clean amp)

MXR M103 Blue Box

Documented together in more than one rig — the Blue Box's glitchy octave fuzz gets extra swirl from the Phase 90 stacked right after it. — also used together by 1 artist

Keeley Super AT Mod (Andy Timmons Full-Range Overdrive)

Phase 90's classic swirl colors the Super AT Mod's harmonic drive after the gain stage rather than adding to it.

Eventide Space

Run the Phase 90's classic sweep after the Space's shimmering, studio-grade reverb and the modulation colors the decay directly. — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Melee Wall of Noise Black

Melee's noise-rock reverb wash is dense enough that running the Phase 90 first keeps the sweep from disappearing into the wall of sound. — goes in the amp's FX loop (or last, into a clean amp)

Cusack Music Delay TME

Run the Phase 90's classic sweep after the Delay TME's reliable echo and the modulation colors the repeats directly. — goes in the amp's FX loop (or last, into a clean amp)

Crazy Tube Circuits White Whale

Run the Phase 90's classic sweep after the White Whale's harmonic reverb-tremolo and the modulation compounds into something genuinely deep. — goes in the amp's FX loop (or last, into a clean amp)

Meris Mercury7 Reverb

The Phase 90's swirl sits best ahead of the Mercury7's reverb tail, so the modulation gets wrapped in reverb instead of chasing it. — goes in the amp's FX loop (or last, into a clean amp)

Crazy Tube Circuits Mirage Dual Reverb

Run the Phase 90's classic sweep after the Mirage's swelling, other-worldly reverb and the modulation colors the reverb tail directly. — goes in the amp's FX loop (or last, into a clean amp)

Amptweaker Big Rock Pro

Run the Phase 90's classic sweep after the Big Rock Pro's fat, modern distortion and it has serious harmonic content to color.

Aguilar Octamizer (Bass Octaver)

Run the Phase 90's classic sweep after the Octamizer's glitchy octave tracking and the modulation picks up that pitch-shifted texture.

Crazy Tube Circuits Splash MKIV Reverb

Run the Phase 90's classic sweep after the Splash MKIV'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)

Walrus Audio Iron Horse

Layer the Phase 90's organic sweep after the Iron Horse's rich, gritty distortion for movement on an already-textured signal.

Hungry Robot The Borderland

Phase 90's classic swirl and the Borderland's ambient reverb both live in the modulation-and-space category, not gain. — goes in the amp's FX loop (or last, into a clean amp)

Hungry Robot Moby Dick V2

Phase 90's classic swirl and Moby Dick V2's ambient wash both work in the modulation space — pair them for motion and depth, not gain. — goes in the amp's FX loop (or last, into a clean amp)

Pigtronix Echolution

Run the Phase 90 before the Echolution so the phaser sweep gets picked up and repeated by the pedal's complex delay. — goes in the amp's FX loop (or last, into a clean amp)

JAM Pedals Octaurus

Run the Phase 90 after the Octaurus so its classic sweep rides the octave fuzz's shimmer instead of a clean tone.

Walrus Audio Fathom

The Phase 90's organic sweep adds motion that the Fathom's own ambient, studio-grade reverb doesn't have on its own. — goes in the amp's FX loop (or last, into a clean amp)
