MXR® Phase 90

The MXR Phase 90 is a classic stompbox popularized by Eddie Van Halen. At present, I own an MXR Phase 90, a Boss PH-3 Phase Shifter, and a Line 6 MM4 Modulations Modeler (with a few phaser patches), so I can compare these three units.The Phase 90 has a single "Speed" control that sets the rate of the phase, so it is simple to use. If there is a single knob, that is a good indicator that the manufacturer feels pretty good about the sound of the unit. In this case, I agree.The MXR Phase 90 is by far the cheapest of these three units. In my opinion, it also gives the best sound within its capabilities, and actually seems to boost the volume slightly. The Boss PH-3 gets a slight volume drop but it is workable, and the Line 6 MM4 has a volume drop that for me is hard to use on a guitar pedalboard because I usually don't leave modulations on for an entire song, but turn them on/off in different sections (unless its a chorus).Of the three, the Phase 90 has the least versatility. You can imitate the Phase 90 sound on both of the other units (the Line 6 MM4 does a slightly better job) and both the PH-3 and MM4 have more sonic possibilities. Also, the Boss PH-3 will give a lot more spacey extremes than the Phase 90 which stays in a "normal" range. But again, of the three the MXR Phase 90 sounds the best of the three at what it can do.Bottom Line:(1) A classic pedal at a great price(2) Great sound & slight volume boost(3) Simple to use(4) Limited sonic possibility, "safe" or "normal" guitar sounds (no crazy extremes)(5) Beautiful bright orange color, you can't miss it(6) Compact size does not eat up pedalboard space

This pedal sounds great, and working properlyIts a keeperJust if you are like me, bought it because you saw someone convincing you that phase90 can be sounded like chorus pedal, buy a chorus, because this effect is deeper than chorus and does its thing very well but cant replace a chorus

Great old school phaser. Built like a tank with great functionality, standard size for modern pedals. Super versatile pedal. I don't think these have as much precision and accuracy is some of the newer phasers by mxr but you really can't go wrong with this pedal.

One of my favorite pedals. If you haven’t used this pedal, you’ve heard it. Add some distortion or overdrive and it produces amazing depth to chunky riffs and deep chugs. I love it. You’ll love it. It’s like magic. Buy this pedal.

The Phase 90 pedal offers everything that went wrong with digitally produced sounds. I've used several Line 6 products over the years, such as the Pod, Spider and Flextone, but nothing can come close to the authentic sound of that tiny phase box.Keep in mind the phase pedal should be used in conjuction with a number of other pedals such as BIG MUFF or some other sustain. This is a simple device, but can tweak your sound toward more retro music such as Sonic Youth.If you want Phase, this is the way to go.

Nothing negative to say about this pedal. Classic sound and style and easy to use. Delivery was fast and exactly as described.

Great quality and sound. Simple to use!

Sounds cool
