Pedals that stack with the MXR Phase 90

Catalinbread Galileo

The Galileo's bright, pickup-tuned boost gives the Phase 90's sweep more top-end presence to move through.

EarthQuaker Devices Chelsea

The Phase 90's classic-rock sweep follows the Chelsea's bright, British-voiced drive for a defined swirl.

Ibanez Tube Screamer

Phasing after the Screamer's drive keeps the sweep defined rather than letting it wobble the gain — also used together by 1 artist

Walrus Audio Fable

Phasing and granular reverb don't fight for the same space — run the Phase 90 alongside the Fable's glitchy stereo wash and each stays distinct. — goes in the amp's FX loop (or last, into a clean amp)

Paul Cochrane Timmy

The Phase 90's classic-rock sweep follows the Timmy's transparent, treble-cutting overdrive for a defined swirl.

Boss OD-1 Overdrive

Run the Phase 90's classic sweep after the OD-1's transparent, asymmetrical clipping and the modulation has real bite to color.

Xotic EP Booster

The EP Booster's fat, boosted signal gives the Phase 90 more level to sweep across without needing to push the phaser's own gain.

EarthQuaker Devices Arrows

Run the Phase 90's classic sweep after the Arrows' subtle treble boost and the modulation has real bite to color.

Electronic Audio Experiments Surveyor V2.5

Run the Phase 90's classic sweep after the Surveyor's reliable, transformer-driven push and the modulation has real body to color.

Keeley Super Phat Mod

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

Fulltone OCD

The Phase 90's classic-rock sweep follows the OCD's firm, thick British drive for a defined swirl.

EarthQuaker Devices '- Speaker Cranker

The Phase 90's classic-rock sweep follows the Speaker Cranker's subtle, transparent boost for a defined swirl.

J. Rockett Archer

The Phase 90's classic-rock sweep follows the Archer's creamy, treble-boosted drive for a defined swirl.

Electronic Audio Experiments Longsword V4.5

Run the Phase 90's classic sweep after the Longsword's baritone, treble-tuned clean boost and the modulation has real body to color.

Blackstar Dept. 10 Boost

Put the Phase 90 after the Dept. 10's tube boost and its classic sweep rides on top of the gain instead of getting buried.

Electro-Harmonix Crayon

The Phase 90's classic-rock sweep follows the Crayon's transparent, treble-forward drive for a defined swirl.

Keeley Red Dirt Overdrive

Phase 90's classic swirl colors Red Dirt's thick, organic overdrive after the gain stage rather than adding to it.

Catalinbread VariOboost

Run the Phase 90's classic sweep after the VariOboost's transparent clean boost and the modulation stays articulate.

Boss DS-2 Turbo Distortion

Run the Phase 90's classic sweep after the DS-2's warm lead saturation and the modulation has real body to color.

Dr. Scientist Frazz Dazzler

Run the Phase 90's classic sweep after the Frazz Dazzler's gated, low-gain fuzz and the modulation has real bite to color.

ProCo RAT 2

Pairing the Phase 90 with the RAT is a documented combo — running the phaser after the distortion keeps its sweep defined rather than smeared by the gain. — also used together by 1 artist

Dallas Rangemaster Treble Booster

The Phase 90's psychedelic sweep works well after the Rangemaster's treble boost, since the extra top end keeps the phasing from getting lost.

Boss ODB-3

The Phase 90's classic sweep sits on top of the ODB-3's fundamental-heavy bass overdrive without eating into that low end.

Boss BD-2 Blues Driver

Run the Phase 90 after the Blues Driver so the sweep moves across an already-driven tone instead of a bare clean signal.
