Pedals that stack with the MXR Phase 90

Colorsound Power Boost

Documented in one rig — the Phase 90's organic sweep rides on top of the Power Boost's own transparent treble lift. — also used together by 1 artist

Alexander Pedals History Lesson Vol. 2

Running the History Lesson after the Phase 90 keeps its analog-voiced echoes trailing cleanly behind the phaser's sweep rather than smearing into it. — goes in the amp's FX loop (or last, into a clean amp)

Analog Man King of Tone

Run the Phase 90 after the King of Tone's transparent drive so the sweep colors an already-boosted tone instead of a flat clean.

Colorsound Overdriver

The Phase 90's classic-rock sweep follows the Colorsound's transparent British boost for a defined swirl.

Strymon El Capistan

Put the Phase 90 before the El Capistan's tape-style echo so the modulation gets carried into the repeats instead of racing past them. — goes in the amp's FX loop (or last, into a clean amp)

Boss DD-200 Digital Delay

The DD-200's wide range of delay and shimmer modes gives the Phase 90's swirl somewhere to trail off once the sweep settles. — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Voyager Mk II

Add the Phase 90's organic sweep after the Voyager's silicon clipping boost for movement on a shaped, boosted signal.

Browne Amplification Carbon

The Phase 90's classic-rock sweep follows the Carbon's warm, clean-boosted crunch for a defined swirl.

Ashdown Geezer Butler Signature

Run the Phase 90's classic sweep after the Geezer Butler's doom-voiced distortion and the modulation has serious low-end body to color.

Browne Amplification Gritador

The Phase 90's classic-rock sweep follows the Gritador's asymmetrical midrange clipping for a defined swirl.

Dunlop MXR Distortion Plus

Run the Phase 90's classic sweep after the Distortion+'s warm, compressed clipping and the modulation has real body to color.

Catalinbread Formula 55

The Phase 90's classic-rock sweep follows the Formula 55's bright, tweed-amp bloom for a defined swirl.

Klon KTR

Run the Phase 90 after the KTR so its classic sweep rides on top of the boost's midrange-forward breakup.

Vemuram Jan Ray

The Jan Ray's punchy, transparent medium-gain drive gives the Phase 90 a dynamic, textured signal to sweep across.

Vox Valvenergy Copperhead Drive

The Copperhead Drive's British-voiced sizzle gives the Phase 90 more harmonic content to sweep than it would get from a clean signal.

Catalinbread RAH

Run the Phase 90's classic sweep after the RAH's balanced, natural overdrive and the modulation has real body to color.

Marshall Guv'nor

Run the Phase 90's classic psychedelic sweep after the Guv'nor's vocal, balanced crunch and the phasing has real harmonic content to color.

Boss RV-5 Digital Reverb

Run the Phase 90's classic sweep after the RV-5's spring-voiced stereo reverb and the modulation colors the reverb tail directly. — goes in the amp's FX loop (or last, into a clean amp)

Ibanez TS10 Tube Screamer Classic

Documented together — Phase 90's classic swirl colors the TS10's mid-forward overdrive after the gain, a pairing with real mileage. — also used together by 1 artist

Friedman BE-OD

The Phase 90's classic-rock sweep follows the BE-OD's tight, hard-rock gain for a defined swirl.

JHS Pedals JHS AT+

Phase 90's classic swirl colors the AT+'s transparent overdrive after the gain stage rather than adding to it.

Electro-Harmonix "Ram's Head" Big Muff Pi V2

Documented together in at least one rig — run the Phase 90's classic sweep after the Ram's Head's thick fuzz and the modulation rides right on top of that vocal midrange. — also used together by 1 artist

J. Rockett Archer Ikon

Let the Phase 90's classic sweep ride on top of the Archer Ikon's compressed drive rather than a bare clean signal.

Boss RV-6 Reverb

Run the Phase 90's classic sweep after the RV-6's ethereal, shimmering reverb and the modulation colors the reverb tail directly. — goes in the amp's FX loop (or last, into a clean amp)
