JIM DUNLOP Phase 90 Guitar Effects Pedal, 6.35mm (1/4") Jack Plug (M101)

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.

Just an absolute classic sound

Not enough phase effect in this pedal for me.

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

Sounds cool

It covers a lot of ground for a one-knob effect. Try it both before and after your dirt pedals. I love it going into a distortion pedal! Sounds great clean too.
