MXR Phase 90

For over four decades, the MXR PHASE 90 has been a mainstay on the pedal boards of millions of musicians around the globe. It doesn’t matter whether the genre is rock, metal, alternative, jazz, world-beat, or if the instrument is guitar, bass, keys, vocals, or strings: the Phase 90 has been there through it all to add its distinctly lush voice to a musician’s tone palette.

MXR

Since 1972, MXR has been a pioneer of the effects pedal market with the revolutionary development of tough and rugged stomp boxes, simple utilitarian designs, small sizes, and 100% rich analog tone. Today, Dunlop continues MXR's traditional pedal line of original MXR classics, as well as new modern classics like the Carbon Copy and Fullbore Metal. However, MXR continues to inspire with new designs. The MXR Custom Shop faithfully resurrects recreations of the long-lost vintage models such as the hand-wired Phase 45, as well as doing limited runs of pedals featuring premium components and highly modified designs, such as the new Custom Comp.

As the other reviewer pointed out, modern effects processors just don't get phasers (or really any modulation) right. You absolutely need this for an authentic early Pink Floyd sound (before Gilmour switched to a EM Flanger around time of the Animals tour). There is a very simple mod to make sound a little more like the classic "Script Logo" version that involves cutting one resistor. I prefer the sound that way, but even stock this is a great little effect that does one thing and does it well.

I'm pretty familiar with this phaser, and I own a few MXR pedals. They are overall a good quality product, and MXR has made quite a name for themselves in the many years they have been around. I ordered a used one, and was shipped one that was beat half to death. However, it works perfectly and I;m sure it will for years to come cause I know how well they are made. I have thrown my old MXR distortion+ to the concrete many times to test it's quality in front of my friends, and it's never given me a problem.

I have several MXR pedals. Every one is superb--except for this PHASE 90 (the non-"script" version reviewed here). This PHASE 90 is worthless for anyone who wants to use it while playing clean, for it adds a tsunami of irritating distortion, a swoosh of sonic dirt. I did some research and discovered that other people who also hate this pedal's distortion suggest some modifications. (Look up "MXR Phase 90 Mods," and "Erik's Corner" will show you how.) I made the "R28," "C11," and "C12" modifications. The result: a slightly improved phaser, one that still churned out plenty of distortion. Finally, I tried adjusting the internal trim pot. On no setting could I get rid of ... you guessed it: distortion. I spent literally hours in a futile and frustrating effort to make this pedal sound merely acceptable. No luck. BOTTOM LINE: IF YOU WANT A PHASER THAT DOESN'T ADD SIGNIFICANT DISTORTION, AVOID THIS INCARNATION OF THE PHASE 90.

Received this as a gift for Christmas. I had been asking for the "script" version, and I think my poor girlfriend just saw the cheaper version and assumed it was the same thing. If you want a pedal that will add a whole ton of distortion as well as boosting your volume about 5 notches, then I guess this is the pedal for you. I find it to be completely useless when using any kind of distortion or overdrive. The signal boost is so significant it's startling (not good if you're trying to create textures or use the phase during transitions). It's not AS noticeable when playing clean, but it's still there and if you combine it with any other effects (reverb, delay) you will notice even more. This pedal will literally alter the tone of everything you have, while simultaneously cranking the volume. Spend the extra cash, get the script. Don't waste time or money on this one. Also, on a side note, why on Earth does MXR put the DC inputs on the lower right side of their pedals???? It's infuriating.

Easy to use, solid construction, great sounding effect = great all around pedal at a great price! Other phasers are similar, but the mxr seems to have a much better sound than all the others I've tried.

There are a ton of phaser options out there - even from MXR themselves - which makes this issue a bit confusing. I'd owned a Phase 90 back in the 80s and wanted another one. A few years ago I didn't have the budget to consider the more expensive MXR versions, so I just got this one.

I think it sounds fine. I gigged with it for years without issue. Yes, there's a slight volume bump, but I think this is really mostly a midrange hump that will alter your tone and give you some distortion, depending on how your amp is set up. I always use it with a clean tone, and I'm used to it so it's not a big deal.

If I were to shop for a phaser today I'd consider some of the other MXR models, as well as versions from other manufacturers which offer a mix knob. A phaser is a very specific sound, but I love it in small doses. For my needs this one works.

When I first started to build my pedal board several years ago, I got one of these, and I tried it our for all of TEN minutes before sending it back for a replacement. I honestly ~believed~ the one I received was defective, and I was stunned when its replacement arrived and sounded exactly the same. Yuck. Don't believe the false endorsements of these products on amazon by Dunlop Manufacturing Inc - don't play your guitar through a ridiculous , thin-sounding, tone-sucking, mass produced piece of junk that goes <~POP~!!!> and <HISSSSSSSSSS!> when you hit the switch. This may have been "good" 30 years ago, but now nearly EVERY phaser option out there - even ones based on this circuit but built by other smaller companies - is better sounding and more useful than this.

As other reviewers have stated, on clean channels, this pedal works great and the transition between on and off is hardly noticeable. So you can be playing through a progression, turn it on for some fun, then turn it off, and the amp level pretty much stays the same.

But if you you are playing through a dirty/overdrive channel and you turn the pedal on, the output level (volume) changes dramatically. As if you had cranked the volume up. This is fine if you use the pedal the entire time, or you compensate for the volume when you need to use it during a song, or if you want that extra boost when you use the pedal. But for me, I wanted the pedal to be fairly transparent without having to worry about settings; so I'll be returning it.
