    Phaser Heaven

    I had this pedal years ago, and wanted that sound again. I knew what this pedal sounded like and was not disappointed when I got the new one. MXR has the best phaser for my style. I've tried others, and this one has the best all around sounds. Thanks MXR.

    This pedal is awesome. I had this pedal years ago, and it made my sound complete. When I started to play guitar again after a long pause, this was the pedal I looked at getting first. Looking at adding some other MXR phase pedals to my line up in the future. MXR makes great pedals.

    Classic! Awesome!

    Great pedal!

    This pedal is awesome! I saw it on so many pedalboards and wondered what it did. I play in a psychedelic/bluesy band and it is so useful. I use it for almost everything now and it's built nice and is one of my favorites now for sure!

    Great pedal

    Awesome pedal, easy to use and it adds some pretty darn cool sounds.

    Excellent phaser, adds a lot of diversity to my effects chain

    I use this a lot for clean channel / acoustic intros, etc. and it adds a very distinctive sound. It's very simple to use and it just works. Sounds great also.

    The Best Phaser

    I bought this initially in 1972 and loved it! It got lost along the way all these years later, so I bought another one. Still the best phaser you can buy. I have had great success using Dunlop products, and especially this the MXR Phase 90.

    Just Right

    What makes this pedal so perfect is Everything. Price, simplicity of operation, shimmery effects, classic phasing. Just drop in a battery and go. Or connect a Dunlop 9v power supply and keep the Phase 90 always on line. The switch is just so smooth and easy to operate.

    I firmly believe that less is more when it comes to pedals and with one button and one pot the MXR M101 fits the bill.

    Classic pedal still giving that great classic sound

    I own the original and this current production model sounds exactly like it. I'm very happy to now be able to keep my original at home where it's safe but not have to give up the sound I love.

    I love this pedal

    I love this pedal. it adds so much color to your tone without any loss of volume when you play a high note on a lead.Most of my effects pedals are MXR. Their products never let me down. Most effects I trade in after a time but not MXR products. The phase 90 is the best phase pedal I have ever used.

    Solid Phaser

    Does everything I need it to in a space saving frame size. I'm a big fan of simple controls on pedals and you can't get any simpler than one knob and an on/off switch. It's well built too, as you'd expect from MXR. If you need a phaser look no further.

    MXR phase 90

    Simple. Does exactly what it is supposed to do. Nice thick sound. Great texture effects. Does however add a slight boost in volume, but it's manageable. Great for the price and it's a classic.

    MXR Phase 90

    I was a little worried after I ordered the MXR Phase 90. Being used to a Mutron Bi-Phase, I didn't know how the MXR would perform. BOY, was I surprised. Not only could I get that "Waylon" and Van Halen phase sound, I also got a great classic "Alabama" sound, too.
    It is built rugged and simple...who could ask for more. I give the MXR Phase 90 "two thumbs up". And kudos to Kurt and the whole Sweetwater staff for excellent service!

    MRX Phase 90

    Excellent guitar phaser. Tried it on a couple of mono synths and didn't care for it. On guitar it is a hair overblown with no way to back it off. But, it sounds great.

    I like the easy simplicity of the phase pedal. Ads a nice complexity to the sound.

    Really good phaser for the money

    Has a great sound to it, a really wonderful tone. I would highly recommend it over any other phaser in the same price range, nothing can touch it in terms of its sonic quality, and it's a great bargain for the money.

    That said, I would have given it 5 stars, but the phaser adds a little gain to your signal when it's on. This can be a distraction in quieter live situations and is uptick in volume is particularly noticeable on recordings.
