About MXR Phase 90

The MXR Phase 90 is probably the most famous phaser pedal in the world. This tiny orange box has appeared on more recordings than any other phaser pedal. It has a thick, nuanced sound that is expressive and satisfying.

There are several versions of the Phase 90, all of which share the same basic sound. All MXR effects pedals are made with a strong metal housing and good quality switches for a long and active life.

The MXR Phase 90 is available at every guitarguitar store and also here online.

Frequently Asked Questions about MXR Phase 90

Question: Which famous players or songs have the Phase 90 on them?
There are loads but here are a few obvious and less than obvious examples of high profile Phase 90 action: Pink Floyd - Shine On You Crazy Diamond (the 'Syd' riff), Eddie Van Halen - Ain't Talkin' Bout Love main Riff (and all 'whooshy' moments on first two albums), Zakk Wylde - loads of Black Label Society sounds, Iron Maiden - Number of the Beast Intro and White Zombie - Blur the Technicolour (main riff).
Question: Where should I put the Phase 90 in my FX chain?
Since phasers are modulation pedals, they should be chained after gain/overdrive pedals and before ambient pedals such as delay and reverb. If you have an effects loop in your amp, we recommend putting the Phase 90 in there. Putting the phase 90 before your distortion will result in an entirely different sound and may be just what you want so give it a go at least!
Question: Is there a sonic difference between the regular Phase 90 and the 'Script' version?
Yes, the 'Script' version has a mellower, less aggressive sound. You can actually get both varieties in one box if you buy the MXR EVH Phase 90. It has a button to switch in the 'script' sound.
