MXR Phase 90

This pedal is one of the simplest pedals on the market couldnt get any easier.

My set-up usually is my 80's Hamer standard-->Electra 602 C compressor-->MXR phase 90--> Marshall MG series 15 watt amp but it varies depending on tunings and what I'm playing. I have the MXR-P90 at 11 o' clock the effects sound amazing at all times. I can get tons of the EVH sounds, country, funk,and some cool metal ones too... sound great if teamed up and looped with a Boss CE-3 rate 2.5 o'clock depth 2 o'clock stereo mode at the left dot.

I can depend on it so much i would put my life on it. But just in-case a freak accident i would have a back up.

I haven't had to deal with MXR yet.

I mostly play Metal and this is a great match especially for those tapping solos!But i do play all kinds of music I feel this pedal is pretty universal.
I have been playing for around 5 yrs now and I am the proud owner of 5 guitars all electric all 6-string.90's ibanez,Zakk Wylde Gibson LP w/guitar heads active p-ups switched them to put the EMG's in my Jackson RR,80's Hamer, and a Dean VMNT Dave Mustaine w/ live wire actives.
Pedals - Electra 70's 602 C compressor - MXR Phase 90 - Boss CE-3, Dunlop Cry baby GCB-95 - Digitech Death metal - Boss DS-1 keely moded - Boss OD-2.

If this were lost I would go right out and buy another in a heart beat.
I love this pedal because it is simply the best phaser I have ever heard and it helps me create music.

If you are thinking about getting a phaser get the Phase 90.

MXR's gear is built to really last.

It's extremely easy to use: You've got one knob. If you can't figure this one out you're retarded.

This is where it gets shaky...
I have a 1980 Phase 90 that I bought off a friend. I like it a lot, but when I turn it on, it sucks out my treble and gives it a very muffled sound. The effect itself sounds great! But the fact that it sucks out so much tone is very disappointing, but I guess that's what you should expect from a 30 year old pedal.

It's very reliable. I have had no issues with it not working. My only worry is that it has no power plug, so the only way to power it is with a 9v, which I just don't trust. I've had the same battery in for about 6 months now, and the pedal still sounds great, but I just don't like that it could quit on me at any time.

Never had to deal with them.

I play a lot of blues/rock, but I have gotten into some psychedelic Pink Floyd like stuff, so the Phase 90 is great for that.
I play through 60th Anniversary Strat-Boss TU2-Line 6 DL4-Ibanez DE7-Phase 90-Fender Hot Rod Deluxe. It sounds great for what I use it for, but something I don't use often, and would trade for something else if given the opportunity.

Like many have said before, it doesn't get easier than this. 1 Knob, 1 on/off switch. So dead easy to get a good sound then? Theoretically, yes...

This is my setup:

Fender MIM Tele - Crybaby - RAT II - Little Big Muff - BBE Orange Squash - Boss ME50 (For the stuff I can't afford seperately! :D) - Phase 90 - Boss RV5 - Orange Crush 30R Hughes and Kettner Edition Blue 60R.

So, first I tried it solo, just guitar-phase-orange.


Biggest disappointment ever.

There is a horrible boost effect when the MXR is activated. Not the useful kind of boost - the pedal makes everything louder, but muffled and overly bassy. This effect occurs no matter what speed setting you use. This is NOT what anyone wants from a pedal.

So then, in the vain hope it might do something else, I put it on my pedal board and tried again. Exactly the same sound as before. It was clear that for clean use it was PATHETIC, but what about with overdrive on? I turned on the RAT. Where before the sound had been sharp and snappy with just od, the phaser made everything sound... I think mushy is the best word to describe it - unusable sound. Then I tried it with the compressor and the Muff - same thing again, just slightly different volumes obviously. Somehow, I made a pretty passable attempt at the phaser guitar sound at the start of "This is the place" (RHCP), although there was still that horrible gain boost there.

Can I depend on it? Yes. It's definately tough, I'll give 'em that. I would use this on a gig with no backup, except of course I wouldn't want to hurt the crowds' ears with such an awfull sound!

Never dealt with MXR - while reading reviews on the internet after a few hours of frustration, I discovered that this was what it was meant to sound like. I would consider doing the mod which everyone says works a treat, but I wouldn't know where to start and would probably break it.

I play anything from Bloc Party to White Stripes, Chili Peppers, Arctic Monkeys etc etc. I have been playing 3 1/2 years. If this was stolen, I would go straight out and buy another (hopefully decent) phaser pedal - just not this one! I love nothing about this pedal - it was a waste of ??70. Can't believe they charge so much for a piece of junk like this. I didn't compare it to anything else - wish I had now - as I reckoned that, this being MXR's (probably) most famous pedal, it had to be gopod, right? WRONG. Anything I wish it had? Decent sound is first on the list.

DO NOT BUY THIS PEDAL!!!!!

I had a ten quid behringer phase 90 clone before - sounded MUCH better! MXR needs to get their act together and seriously lower their prices.

1 Knob for controlling the speed, very easy. It also has an internal pot for controlling the depth (stock is at 9:00, I increased it a little bit, about 11:00).

I've got the reissue. Out of the box doesn't sounded very well. When kicked on, the volume increased a lot due to a midrange kick. Not a subtle effect, not very vintage. Rate for stock is 4.

But I've done the R28+C11+C12 mod (the easiest in the world, it only takes 10 minutes) and the effect became glorious. The best phaser I've ever had, very subtle, very vintage sounding.

(Gear: Gibson SG's -->> Boss CS-3 (modded) >> MI Audio Tube Zone >> Ibanez TS-9 Tubescreamer >> MI Audio Crunch Box >> Boss GE-7 >> MXR Phase 90 >> Ibanez AD-9 Analog Delay -->> Fender Hot Rod Deluxe 1x12" + 1x12" Marshall cab loaded with a Celestion Vintage 30).

A tank, try to destroy it, you won't be able.

I've never contacted MXR/Dunlop, I don't know...

Remember: the mod is indispensable

1 knob, 1 switch, bright LED. It doesn't get easier.

Here's my rig:

Epiphone Sheraton II >> MXR DynaComp >> Vox 847A Wah >> MXR 10-band EQ >> BBE Green Screamer >> EH Big Muff Pi (Russian) >> MXR Phase 90 >> Boss TR-2 Tremolo >> EH Holy Grail Reverb >> MXR Carbon Copy Delay >> BBE Boosta Grande >> BBE Sonic Stomp

Before the mod, this was maybe a 5 (charitable) because it had an ugly mid boost and abrasive distortion if either at high volume or with any gain stomp boxes on.

After R28 mod (also clipped the two capacitors, I forget which at the moment) the mid boost and distortion was gone and the sound takes on a nice phased warble/shimmer (depeding on Speed). I like to use the Phase 90 with the EH Big Muff Pi, it has a very psychadelic, trance-like sound. (Worth noting that the R28 mod is about as simple as a mod can get; you simply remove a resistor and two capacitors. At the same time, it DOES invalidate your warranty, so be careful.)

The simplicity of the pedal is nice, however you do sacrifice a lot of control since you only have Speed rather than Depth control. This wasn't a big deal for me when I first bought it, but after a while it has become a slight issue; I have been considering a Phase 100 for this reason.

The Phase 90 is not true bypass (and I've heard that modding it to be so is a pain in the butt, for you modders out there) but I notice little tone difference in bypass mode.

Well built, like all MXR stuff it comes with a nice knob cover that allows you to adjust the Speed with your foot in a gig situation without breaking the knob off.

The switch it pretty sensitive, I have accidentally turned the pedal off immediately after turning it on and vice versa a few times. On the other hand, if you can develop a soft touch (or step, or whatever) this might help the switch last a little longer.

Not dealt with them

Can't get a much better analog phaser for this price.

I have been thinking about buying the EVH Phase 90 and using this as a backup; I recommend demoing both if you get the chance.

Well worth the price if you don't mind that it doesn't give you a lot of options to play with.

ultra easy

I got this pedal and took it to my strat+tube amp at home. Playing at regular volume sounded great. I was very happy. Took it to a rehearsal, with amps cranked up, and then when hitting the button, there it was! that mid boost that made it unusable. Came home disappointed and started reading this forum and others. Then, I learned about the r28,c11,c12 mod.
As the pedal was unusable for gigs, I took some tools, a diagram on the web, and proceeded to open the thing.
I have never done this before, but I read some horror histories on the web and I was very careful. The tricky part was to clip the little legs of the bugs. A nail clipper (not the biting part) did the trick. I took one leg out of each and left them pointing up (standing).
Put the thing back together, and WHAT A DIFFERENCE! The sound was clear, smooth and subtle. I could not let go of playing for the next 2 hours at least....with Mod this gets a 10, without mod 7

solid, build like a tank, will live forever

I destroyed the warranty by applying the mod....I would say 10 just for the dealer word of having it back if not happy.

Get this asap.

It only has one knob and it sounds way too good for me to care that it doesn't have more. It's way easy to get a good sound from it.

It sounds killer. The reissue is a hair more trebly and has a slight distortion and midrange addition to it when compared to the vintage 74 reissue but I love how that sounds. The pedal is all in all way more extreme sounding than the vintage 74 reissue. Don't believe me? Go to you tube and check out the shoot outs that people do. There's no need to spend a ton of money on a killer phase sound. People get way too caught up in the vintage nonsense. Listen with your ears and not your eyes.

I can totally depend on it.

I love it. It sounds great on clean or high gain settings. It's way more extreme than the script version. Listen to the you tube shoot outs and hear what I'm talkin' about. The reissue is the way to go for someone who wants an extreme phase sound. No need to break the bank for the more subtle reserved script version.

It's so easy to use. Press button once and effect is on press again and it's off. There is only one control knob on the pedal (speed.) Battery life is good. Doesn't come with a manual (why would you need one?) Many people don't like the block logo phase 90 but I think it's great. I don't use effects very often and I use this when I need a bit of character in my sound.

My setup is Shure PGX14 wireless to Fender HSS Strat/Fender 40th Anniversary StratGibson Les Paul/Fender Tele/Peavey T26 to Dunlop Crybaby Classic -> MXR Phase 90 -> Rocktron Banshee or homemade talkbox (changes nightly) -> Line 6 POD (for distortion only) -> Peavey Windsor head (for Rock/Blues) or 1970 Kustom K200B-5 (country/latin rock) -> Behringer BG412F 4x12 straight cab. It's only noisy if the battery is low (like all Dunlop/MXR pedals I have used.) The phase sound is very good. I set mine at 9 0-clock always. My band play Classic Rock, Southern Rock, Classic Country, Modern Country, Texas Blues, Bristich Blues, Latin Rock, Reggae, a bit of Disco, some Alternative Rock and Bluegrass. People seem to like the variety. I use this pedal on songs that need a little something more than a dry sound (we don't like using anything artificial). I don't like my POD's Flanging or Chorusing sounds so I use Phaser.

Very tough pedal. I don't have a backup phaser and don't think I'll ever need one.

As I said earlier we play just about ANYTHING and on the songs I use this it's great. It helps me get creative. If you want a great phase effect this is the one to get. People have been using this for 30+ years and it's still the standard and it's pretty cheap too!

It couldn't be any easier to get a good sound out of this little brick.

I'll give it a 9 because nothing's perfect, but I don't have any problems with this. It's a re-issue, and I think it sounds great, exactly what I was looking for.

Who knows? MXR stuff always feels like you could drop it off the roof and it would still work, but I had a Distortion+ in the 90s that crapped out on me after a few years of light use. Again, who knows?

Never had a need, and hopefully I won't have to anytime soon.

Frankly, guitar players get way too hung up on names, labels, "original" this, "better" that. "Oh, I would never play one of the re-issues", blah blah blah To me, that's all meaningless drivel. I have no interest in overpaying for an original Phase 90, this re-issue suites me just fine, and sounds great. I guarantee you that 99% of the cork-sniffing tone snobs out there wouldn't be able to tell the difference between this and an "original" in a blind test. But who cares, play what you like. Just don't look down your nose at players who don't need to project the boo-teek contents of their pedalboard onto the back wall so that everyone in the audience will be impressed. Hey, I love gear, and I love talking gear, but it just gets ridiculous sometimes. I've been playing for 25+ years and get regular compliments from the tone generated by my pocketbook-friendly rig: Am Std strat into various pedals (Barber Ltd, Rte 66, Digidelay, etc) into a Peavey Delta Blues.

One nob and a switch

5 before the mods 9 - 10 after.

I bought the pedal with a strong assumption that I would be doing the r28 mod, but played with it before doing so. I knew that unmodded it might not quite be what I was looking for, but, when I plugged it in it was far worse than expected. It not only added phase, which is what it is supposed to do, but it totally changes your tone and sound, adds a mid range boost, and that nasty distortion when hit hard etc... I have other pedals to color my sound, distortion pedals, wahs, equalizer etc... The last thing I need is unwanted unadjustable tones from my phaser!! - Kind of wierd why they build it this way.

Anyhow, the good news. Given the above, I clipped the r28 mod, and plugged it back in. This made a substantial improvement, greatly reduced the mid range color and pretty much eleminated the distorted tones. One snip turned the pedal into something useable and musical, but, it still wasn't quite the phaser sound I had in mind, it was still a bit too much on the bottom of the phase i.e. it washed the tone too much kind of like an extreme backed off wah setting.

So, I proceed to clip the C11 and C12 caps. After this it was really sounding good, a nice sweet phase that didn't change the volume or color the tone when kicked in, but even more tweaking was in order. In researching the mods I picked up suggestions to play with the internal pot adjustment, especially if you do the C11 and C12 mod. I did, tried it in different positions and found that turning the pot a little bit more clockwise added back a bit of deepness to the phase without adding any unwanted tone changes. - I am very pleased now, I feel like I got a nice transparent musical phase that is much more akin to what you get out of more expensive units for $70!!

Rock solid construction

It is a fantastic value after the mods. If you aren't willing to modify the pedal, at the very least the R28 mod, be careful, the stock pedal really adds alot more than just phasing to the tone, you may like it, but I really didn't.

If you have questions, you can pm me on the Harmony Central boards under Mickslick

It has one knob: Speed. Effects can't get any easier than this! If you can't figure out how to use this pedal... you need to give up on effects pedals all together. All you do is plug it in and click it on/off.

I love the way this effect sounds on a bass! It sounds great on guitar too, but I think it sounds amazing on bass. It adds a little bit of an "underwater" tone that is just enough to give you an edge. It doesn't rob the low end, and it adds a sparkle that can be great for a slow melodic lines while still being equally effective for a greasy funk riff. The first time I tried this pedal I knew I had to own it!

This thing is built like a tank. I don't abuse my gear, but if I did... I'd guess there would have no issues with this pedal. It is remarkably solid.

I've never had to engage them so I have no opinion.

I think all bassists should try this pedal. It sounds great on a bass! I've had several pedals come and go, but this one will always be on my pedalboard. I have only one complaint: I wish it was true bypass. That's the only thing this pedal is missing... other than that it is perfect.

This particular Phase 90 is the "script" model or "reissue" model. Beautiful pedal and MXR did a fine job in recreating an original. The only added feature that this model has is the red LED, which is a plus over the original.

Easy to use out of the box. One knob. Tone it to your preference (speed). That's about it. Not much to say. I normally keep it at about the 11-o'clock position. Perfect for me without too much of a phase effect.

I never played the original Phase 90 (script) pedal but have heard about its legendary tone from great artists like EVH, David Gilmour, and others. I was hoping to recreate the tone from EVH's "Unchained" version but with my wimpy setup of a stock Strat and a 60-watt Fender Cyber Champ, it proved difficult. Plus, EVH uses a harmonizer, modified amps, and a freakish guitar setup to get that sound. Close, but no cigar.

The pedal does produce some nice, wavy, phase tones, but in all fairness, my setup isn't what I consider a "professional" setup. Simple Strat hooked-up to a simple 60-watt Fender. I was expecting a bit more, but that may just be my high expectations.

Decent pedal. Not earth-shattering. Will take time to "tone in" my sound I guess.

Here's where this pedal failed me. Literally.

This pedal failed after 10-minutes of use right out of the box. I first ran it with a 9-volt battery and all was fine when suddenly, the pedal started to fizz-out and sound weak. The red LED was lit up, but the pedal sounded like crap. A few minutes later, no phase effect at all was coming out of it, so we figured it was a weak battery. Just to make sure it wasn't the battery, we plugged it into a MXR adapter. Same result.

Here's the scary part. A few minutes after plugging it into the MXR adapter, we started to sense a "burning electrical parts" odor. Augh! Sure enough, the pedal's electronics were fried! The pedals LED was still on, but no phase effect and the bypass still worked. Bottom line, the pedal was dead.

I immediately called MXR the next day and got a RA (Return Authorization #) to have it replaced. The guy on the phone at MXR was understanding and didn't question it other than "What power adapter did you use?". He issued me an RA number and told me to expect a replacement back in 2-3 weeks. We shall see. I will update this review after I get my pedal back...if I ever do!

As mentioned above...we shall see.

I play mostly classic rock like Led Zep, Boston, Cream, Pink Floyd, etc. Hoping to recreate some of the 70's sounds. Have been playing for about 10 years total (off and on).

Have tried other phase pedals but was disappointed by their tone. I was hoping this reissue would do the trick.

I'll give it another chance when I get my replacement. Only this time I'll put it thru a Les Paul and Marshall amp to see what it can do. As for the EVH sound, well...I don't have a monster rig so this will have to do!

Its one knob. Marked speed. If you have difficulty then there is something wrong with you.

Sounds great! I used to have a EHX small stone and before that a boss PH-2. The boss was too sterile: I can imagine wanting that kind of effect sometimes but its not really me; the small stone was ok, but the volume drop was a problem plus the colour switch down was too weak and the colour switch up too strong: the phase 90 falls somewhere between the two colour modes of the stone but without the volume drop: perfect! Nice and watery and very clearly analog, no volume loss (infact a bit of a boost! I'm told this can be got rid of with the R28 'script' mod). The distortion that people go on about is there, but its is NOT a big deal (Im told the R28 mod solves that too): I can only pick it up when strumming hard or when using a clean boost, its a small price to pay! I use it in the following setup:

Fender jazzmaster/Gibson les paul faded special--
-Barge Concepts BB-jr fuzz--Keeley proco RAT--Boss Blues driver--Loop Pedal (Loops in--Korg DT10 tuner--Boss PN-2 tremolo--EHX small clone--MXR phase90--)--Boss DD-20 giga delay--Fender Blues deville 212 60W combo

This pedal completes my setup... I want to stop spending money!

Never had an MXR pedal before last week...seems sturdy...wouldn't be suprised if I have to replace the footswitch in the future (its not true bypass at the moment...would probably get a good quality 3DPT footswitch when it comes up, but bypass isn't a problem as I loop all my modulation pedals anyway.)

Not a clue. Doubt they'd be much help, more important stuff to do than dealing with the cheapest pedal in their range.

I play indie/grungey/experimental rock along the lines of sonic youth, trail of dead, silversun pickups, sleater kinney, ikara colt, nine black alps, minus the bear etc etc. This pedal does its one trick beautifully and is all I'll ever need from a phaser, but if you're after a several-trick pony I'd go for a boss PH-3 or something similar. if you're more plug in and play then this is for you! I got interested in it not because of van halen (though my brother says it sounds perfect for playing ****** 80s metal) but coz thurston moore used it in the final 15 min noise part of 'the diamond sea', just after the final (quiet) chorus (8 mins in?) when he starts picking that em7/9 chord. Go listen. Thats the sound.

Nice and straight forward - plug in, one knob to twiddle and you're away! The knob has a large rubber bit around the outside (can be removed) which allows you to adjust with your foot while playing in a live situation - handy that!

Good analogue sounds with quite a lot of variation as you turn the knob. I go for about 2 - o - clock myself. Works well distorted and clean, and all points in between, though I'm rarely extreme. I use Marhsall heads, 4x12 cabs, a boost pedal and a tremelo, with a little reverb, using old teles, strats and SGs. All sorts of music covered from rock to punk to blues to alt country.

My only criticism is that the pulse gets too noticeable on a lot of settings. To me it has the one sweet spot, although the extreme stuff is great for short term efect.

Mind you, it's my third choice behind a 1977 Boss PH-1 and an electro harmonix small stone. Having said that, those are tough acts for anyone to follow, and I'd use no other than these three now(but not at the same time...).

Very reliable. Never let me down. Nice and small on the pedalboard as well, though battery access is a pain (4 screws)/

Not needed it!

Works well with a load of styles as long as you keep it in the sweet spot(though Eddie VH made it famous).

1 Knob! if anyone gives this less tahn 10? whats going on :)

I have a 1982 Version and it sounds great! I get no distortion at all which people complain about with the re-issues :) I have never used the latest model? all I know is that I get a very warm and lush clean Phaser sound on whatever setting I put it on :) This nails Pink Floyd! well, Mr Gilmour used this pedal :) anyway, if you listen to dark side of the moon album, thats the sound I get out of this pedal! I don't know if the 70's script sounds any different? but this early 80's version is top notch, I don't think I will buy another Phaser pedal again :) I also own the Dunlop reissue MXR Phase 100! it doesn't match the quailty of my older phase 90! makes me feel annoyed! why don't they build the modern pedals with the parts they deserve to have! re-issue owners are missing out on something that should have never been messed with from the start! im not saying the new stuff is rubbish, you can mod a phase 90 :)! im just saying when the original MXR made something so great! why did Dunlop have to mess with cutting costs on parts etc! it stinks! I think people deserve to have what started the popularity in the first place! I will add that its good that Dunlop have added a DC input on the new stuff :) my pedal has something different? a small hole? one of those different type inputs for power

Can I say I think this is tougher than a boss! seriosuly, this thing is solid like a tank! no signs of weakness!

I own the 1982 version, this pedal gives me the phase sound I like :) I won't be selling it or buying another phaser :)

It's a one knob wonder. you twist the knob to a point where you're happy with the sound and you're set. It helps a lot that the pedal sounds good at almost all of the settings.

I'm using it in between an epiphone goth thunderbird bass and an ampeg b2r head. It sounds incredible with the knob at about 11:00, theres a nice slow wash, I use it on about 1/3 of all of my bands hard rock originals (www.myspace.com/ataraxia1). There isnt any noise or hiss.

It seems incredibly reliable and I've never had any problems with it. I would gig without a backup to it.

I bought the effect from Chris Chiandusse at Guitar Center who was incredible to deal with. Very friendly and definately stands behind the products he sells. If I ever had any problems with the pedal I would take it back to him before trying to go through MXR.

I play bass in Hard Rock songs in the same vein as Disturbed, Black Label Society, and alice in chains. The pedal fits in perfectly with a lot of the cleaner passages in our songs.

If it were stolen I would buy another one in a second from Chris at GC imidiately. The pedal definately plays a part in my creative process, It just sounds great.

Simple to use, one knob. Just plug in and kick the switch.

When I first tried it. I gasped! What the heck is the clipping and unwanted distortion from a $70 unit, it sounded like rig and my $2000 Les Paul cost $2.
Then I did some research about the R28 "script" mod, and tried not to panic. I thought, "if I use this live stock, my band will laugh at me" it sounds like *&%$.
First I toyed with returning it for the $130 EVH Phase 90...
Then I sucked it up, got ballsy and went ahead and did the R28 mod myself and removed the R28, C11 and C12 resistors.
I tried just the R28 first, but it still distorted for me, bummer. So I was even ballsier and removed the C11 & C12 also. I reluctantly put the orange beast back together, having thoughts of, Oh no! what did I just do! I though I just threw away $70. WRONG! I just successfully did the 'script' mod myself and it sounds better than ever, this is now the custom shop script for a third of the price, perfect!

It's built like a tank, compared to the cheap plastic weak Danelectro chicken salad "univibe" I just replaced the this MXR.

Don't Know

The rating went from a 1 "pre-mod" ...
to a ten "with mod" I lucked out big time and saved money.

One knob and a switch...ok? Ok...then let's begin.

I bought a stock one from Dunlop for the sole purpose of doing the famous R28 "Script" mod. I played around with it pre-mod to get a feel for it. The phasing was very upfront and syrupy...pretty cool overall. I didn't notice a whole lot of clipping or distortion that is a common complaint, but I didn't really pound this thing too much. There is plenty of range in the Rate control. I can't believe I didn't order one of these sooner.

So I pulled that bad boy apart, snipped the R28, C11 and C12 whatchamacallits and went back to work. This time, the swirl became broader but more subtle. At lower rates below 12 o'clock, the way the whole thing glides and turns over is fantastic. I really like the movement it adds to chords and single note lines alike. The signal was noticably cleaner.

While I definitely like it better post-mod, pre-mod it's excellent as well. I kind of wish the post-mod version had a little bit more depth to it, but I still dig it nonetheless. I think it's a winner whether you keep it stock or do the mod. I may even by a second one and keep it stock just to have it. My best advice is that if you like it well enough stock, it's perfectly respectable to keep it that way. If you want to clean it up a bit and bring the depth down, the mod is the way to go.

This thing has earned a ride on the pedalboard. I love it.

No issues here.

I've been playing longer than I haven't been playing and I've hit all styles at some point. I like Fender guitars and Vox amps. I have lots of other MXR effects and really dig them all.

This is one of the better effects purchases I've made in a while. I like having a lot of effects around to experiment with and suffer from G.A.S. the same as anyone, but this is something I can see myself using for a wide variety of things. I can definitely see the reason why this thing is considered a classic. At $70 it's a worthy investment.

The R28 mod is a hugely popular mod for this pedal, and it's very clear why. It does give it a vintagey old school sound that I imagine is pretty close to the original Script versions (I've never heard one in the flesh, but if the descriptions of the originals I've read and heard are accurate, this seems to get real close). But whether it's really all that necessary is up to you. This thing is great right out of the box.

one knob...can it get any more easy than that?!!!

the battery compartment is inside, and 4 screws must be removed. that can be a pain, i am sure if i play live with one of these and ran out of batteries, i would have to just unplug it. i may invest in a dunlop "brick" power supply.

oh, and if you are thinking about using that rubber knob grip that slides over the knob, do not use it, unless you are planning on leaving it on there forever! Because you have to use the wisdom of solomon and the strength of sampson to remove it!

sound quality. nice. you see, i have 2 of these. and that legend about the r28 mod is more than a legend, it makes it "script" just like they say! i have 2 phase 90s, and one of those was pre-modded when i bought it. and the bandwidth, and range of harminics is so much wider and more brilliant....GORGEOUS! i think i am going to do this mod to my other one!

2 of these pedals, set almost exactly the same, perhaps just a slight difference in rate, sounds INCREDIBLE! ANALOG BABY!!!

i see it as dependable. as i said previously, i think i want to get that dunlop "brick". a higher milliamp supply does improve the sound quality and reliability! i am not sorry i bought these!

follow the instructions and you should be fine. dunlop only will honor a waranty if it is the neglegance of them and not you. all i can say is, even if it does void the warranty, have the r28 mod done...it will be worth it still!

i am not with a band, per se. but, i do some home recording, writing songs, etc. i have been playing for over 20 years, longer than i havent, really. and i must say, so far, mxr and electroharmonix are my favorite manufacturer of stomp boxes!

Very easy to useEven with all the presets (kidding)

Any thing from EVH to Led Zepp,no Quarter

29 years and still going

Mine is a REAL MXR Phase 90 but Dunlop is pretty cool, They fixed my old Vox Wha for me back in 1989 for free

There is a way huge difference in a real vintage MXR, Has to be from the 1970's Some of the Dunlops can sort of sound OK,but with that red LED it does somthing to them,that why all great fuzz box's Never have a LED.So if you buy a new P-90 better check all in the store and try to get the best one.But if you want that EVH or Led Zeppelin sound,get out the visa and pay trew the nose for a Real one.And if you try to get one on ebay,be VERY careful,most are reissued ones from the late 1990's A real one will say MXR and the date and year on the POT,so be careful on ebay Beat to go to a vintage dealer or guitar show and pay the $150.00 to $200

Two jacks. One knob. Easy.

I use this with an SG and a Hotcake pedal through an old 70's Ampeg and I love the sound I get with it.
Admittedly, it's the only phase pedal I've ever used, but I think it's amazing. It never screws up my guitar's tone adversely, and if it weren't for the fact that it would sound silly, I would leave it on all the time.
I leave it on the lowest setting always and it doesn't do the typical HUGE sweeps that make phasers often sound stupid.

It's an MXR... steel case with one big rubber knob. These things would survive a nuclear blast.

I remember spending a lot on this pedal, but I will forever keep in in my effects chain.

Very easy. Mainly Because it only has one knob and a footswitch. You need a screwdriver to reach the battery, and the power input is awkwardly placed.

"It sounds terrible". I've used this pedal with a variety of guitars, and the single coils understandably suffer less than the higher output pickups. Hit your strings too hard on a guitar with humbuckers and the thing will distort your signal to shit. I'm not talking about about thrashing away at the strings, I mean anything above gentle picking. I tried this in the store beforehand with some old telecaster with low output pickups and didn't notice anything then. I haven't read the the rest of these reviews so I don't know if someone has mentioned it, but it's not a one off - I made a post on a guitar forum about this, and everyone who replied acknowledged the same issue with their own phase 90s. People who didn't notice this either don't have very sharp ears, or are playing through a shit amp/guitar anyway. Either that or MXR are extremley inconsistent.

One more important thing, is that when the effect is switched off, it will still alter your signal, distorting it in a way similar to when it's on but with a less noticable effect.

When it's not distorting your signal it souns pretty nice clean, not so good distorted.

I can't, or see how anyone else can, use this pedal.

If you have trouble getting "your" sound out of this thing you might want hang up your guitar and try the drums or something! One knob, easy as pie! The manual,like anything you buy from Dunlop is for a wah wether you buy a wah or not! Not needed with pedal anyway...

I'm using this with a silverface Twin Reverb (135watt) first into a Boss TU-2 tuner, Ibanez TS-9, Boss CE-5, MXR phase 90 and Boss DD-3, Finally (sometimes)into my Crybaby wah. Ultimtaely my tone comes from either a Les Paul studio or '72 telecaster deluxe. Okay with that said lets review this sucker: The phase is great,very warm and lush from really slow to fast modulation, however if you play percussive like I do,(reggae) your gonna hate this thing.I play mostly clean and do NOT want any extra distotion coming from anything but my tubescreamer! This thing breaks up (clips) like you wouldn't believe...stay away from this if you want maximum clean headroom...

Its brand new and its Dunlop so I'm sure its reliable and its built to last, just not for me!

N/A

Like I said I play reggae music and this pedal would be great for someone that plays dirty (distortion). For me I like to maintain tha max clean headroom I can i.e 135 watt Twin (no tube break-up) and this one aint for me. I read the reviews and shoulda listened...I'll stick with my PH-3 I guess

Classic MXR, easy to use pedal

I use a valve amp and humbucking guitar. Extremely warm tone.

Ive had mine for about 3 years, had problems with my boss delay and small clone and the phaser has outdone them all. Built in very solid casing, very very reliable pedal.

no need

versatile pedal for rock blues, cheap way to get an authentic van halen sound.

incredibly simple ....one knob!
s

I use very few effects, in addition to the phase 90 , I use only a crybaby.
I find the sound when playing clean to be extremely soothing, very well balanced.
When playing with heavy distortion the classic EVH sound can be recreated. rub a palm to the strings and you're the atomic punk!

Built solid!
I can't imagine any probs

never needed

I've been playing about 20 years.
works great with my strat and/or my vintage gibson sg
been using the pedal through a series of marshall amps from a valvestate up to a vint. plexi with mesa cabs
mostly play hard rock to a rock/blues mix

I love this pedal, and would replace in a second if stolen!
Don't even question buying it...just dig into yer wallet and git it done!!!!!
