Not just for guitars; it works well with bass, keyboards, and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble with endless vintage vibrations in between. The MXR M-101 is powered by single 9V battery or Dunlop ECB-003 AC Adapter

This is a very nice pedal for the price point. Its small so it fits on a pedalboard very well, uses standard 9V/100mA power so most pedal power units work great. These MXR pedals (I've got a bunch that use this same size box design) all have a slight drawback. (For me anyways) The power plug is on the side right next to the input jack. On a crammed pedal board it can be a pain. The tiny rubber feet on these size MXR pedals pull right off so you can stick a velcro strip on easily. The main thing is the tone. Its quite nice. Ive certainly heard better but for a basic phaser this is a fantastic unit. Like the other MXR pedals in this housing, its very tough, being made of all metal with a quality switch that seems to last very well. The drawback to this pedal are not really a drawback because its obvious before you buy it, but, anyways.... the drawback is the single speed control knob. It doesn't have any "features" really. You just adjust the speed of the phasing sound with the knob and thats it. It doesn't seem to color your sound when its off. I don't know if its true bypass or not. One final note: this pedal sounds best used between your guitar and the front of the amp. Trying to use it through an amps effects loop will not work well. At least not for me. If you need a simple, durable, nice sounding phaser, this one will work great.

I love this pedal. The only reason why it gets a 5 for overall rating is because of an issue that this pedal has. I bought one of these a month ago and thought something was wrong with it so I sold it and bought another one about 2 weeks ago and it still has the same problem. If you use this pedal in a clean tone with Humbuckers it sounds distorted. If you run the pedal through overdirve or fuzz it sounds fantastic. The only way to get this pedal to sound good in a clean channel is to use Single Coil Pickups. Thankfully my guitar has Coil-Splitting so I waws unable to avoid the distortion. After doing some reserch I found out that this re-issue has a Low Input Threshold and because of that if you use Humbuckers the pedal sounds distorted. So beware of this if you are planning on purchasing this pedal and you only have humbuckers. But other than that flaw, I love this pedal. Sounds very organic and rich.
Only one knob. You only need one knob, thats the beauty of this pedal. It adjusts the speed only. This pedal does not need any other knobs, it is that easy.
I don't think that regular use as a studio musician or giging musician will break this pedal unless you abuse it. Built like a tank.
it is a great deal considering Boss pedals are more and they are not analog like this pedal it.

Stopped working

By Eric Fulmer

from New York City

Comments about MXR M-101 Phase 90 Pedal:

After owning this pedal for about a year, it stopped working, just sucking tone and lowering my volume when it was turned on. It was a good pedal before that, but I can't in good conscience say that something that stops working after a year of light use is a good product. Try better next time, Dunlop.

Phase 90

Comments about MXR M-101 Phase 90 Pedal:

Simply put the good old standard. I've tried others even more expensive and this one is the best. Looking for a quality phaser look no further.
Does what it's supposed to do.
Wonderful pedal for the price
Can't beat the price.

    Love this one. One would wonder how much different settings you could achieve with one knob. The sound is wonderful and it is very responsive before distortion pedal as well as after. I like my phase 90 after distortion. The sound is creamy and larger than life.

    MXR Phase 90

    By CreepingSeth

    from Northwest PA

    See all my reviews

    Comments about MXR M-101 Phase 90 Pedal:

    I'd suggest a "classic script" version over this one, especially if you use high gain or active pickups. The "classic script" phase shifter pedals from MXR sound a lot smoother. It can sound harsh at times depending on where you put it in your signal chain and also can add extra distortion to your signal, which my I run it through it through my loop.
    Not much
    It's built like a tank.
    IMO you're not getting much for the price.

    Comments about MXR M-101 Phase 90 Pedal:

    I've been playing for almost 20 yrs now and mxr is still one of the most simple, reliable, awesome sounding pedals out there. specialy this phase 90 which help shape the brown sound of EDDIE VAN HALEN, which got me to start playing guitar to begin with. hook-it up for that 70's funk or that mean brown sound, you won't be sorry! a must have for collectors or part your gig pedals. this pedal is simple and if you cannot figure this one out, they always need gas station attendants.

    Not bad for phase pedal on a budget

    By guitarjunky97

    from Stuarts Draft, VA

    Comments about MXR M-101 Phase 90 Pedal:

    I just recently purchased this pedal while it was on sale for 56 bucks and its a nice pedal. Well built and will outlast anything else, the phase knob glows in the dark which is nice in a dark room. It doesnt have a ton of features but it works and you can get a lot of different sounds with just one knob. I also would recoomend getting a 9 volt adaptor or it will eat batteries like there is no tomorrow.

    Great all around phaser sound.

    By Matthew Rogers

    from Texas

    Comments about MXR M-101 Phase 90 Pedal:

    Great for any style music, easy to use with only one knob to adjust. Just wish MXR would come up with a phaser that includes a tap tempo function. Now that would be really useful! Also, mine pops when I hit the bypass switch. which is why I gave it this rating.

    This thing is cool if you don't try to go overboard. Keep it set around 8-10 o'clock for some nice effects. I own several MXR pedals & have NEVER had any problems (of course I'm not out touring anymore) Buy it, you'll like it!

        Comments about MXR M-101 Phase 90 Pedal:

        I own a TC Electronics chorus/flanger and it is great, but this pedal has more depth and character. I was looking for a sound to use with my Sick As pedal to get that swampy sound for a new original song I wrote and this pedal fills the bill. This is my third MXR pedal and I keep all three on my pedal board. If you want the best flanger at a great price, get this one.

          Comments about MXR M-101 Phase 90 Pedal:

          This was a replacement for my classic 80's issue MXR Phase 90 pedal that finally gave up the ghost. The sound and controls are true to the original. Used to augment my acoustic, its moderate size makes it very compatible with my pedal board designed for newer generation mini-pedals.

                When I got this pedal I was excited, I had wanted one for about 4 years and finally decided to just break down and get one. After playing it for awhile I was a little let down, in addition to the phaser effect it gave a small gain boost that was undesired. I wasn't a big fan of it. I considered returning it, but then as I was about to bring it back I decided to play with it again just to make sure I wanted to get rid of it. All of a sudden I fell in love with it again, even with the small gain boost! I have it one with almost every song I play, it adds just a small flavor to everything you play!

                Comments about MXR M-101 Phase 90 Pedal:

                It doesn't have much control for the phasing, but that is not bad news at all. It gives a lot of nice phasing great tones. If you want more control over the effect buy another one. Nevertheless, I think you should get another one only if your music is based on this effect, that way you can have more control of it. Otherwise, this is a wonderful machine. I love the way it sounds with my distortion. With the clean sound, just with a little of it, sounds incredible too, specially for those slow songs. Another turn on is the price; it is very economical. Like I said before in other reviews, you can't go wrong with MXR. Among other good brands like Mad Professor, Earth Quaker Devices and TC Electronics, this is one of the best
