The Phase 90 with foot control!

From the MXR Custom Shop, the Variphase is a killer twist on the classic Phase 90. Variable speed control is operated by your foot, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Vary the speed from a subtle, long cycle to a fast, watery warble, and everything in between! On/off switch, volume, and mix controls. Uses 9V battery or optional Dunlop ECB-003 power supply.

Variable foot-controlled speed
Volume and mix controls

Watch out

By Mr Sauce

I agree with one of the's a strange pedal with lots of strange things about it. Here was my experience:- It's heavier than I thought, thereby making me think "this better be good!"- It comes with no instructions, just pamphlets for other pedals- For whatever reason, it took me 5 minutes to get the battery in the right position so that I could close the cover. - The pedal is on a spring, and is always in the heel position. To activate it, you press down.- When I activated mine, I got all this hiss in my FACE.- The lowest volume setting on the pedal was higher than the input, thereby causing the signal to boost whenever I stepped on the pedal (which I don't want)- The intense setting (toe down) sounded like crap, frankly. I couldn't find any good way to use it. On the plus side, it's built like a tank. So I would say that if you like a phaser that you want to control with you foot all the time, and that boosts your signal while at the same time giving you hiss, then this is the pedal for you.I am returning mine.

Not the same pedal as in the picture

By Anonymous

from Undisclosed

The Variphase pedal I was sent was not the same as the one in the picture. It's the same model, CSP-001, but mine did not have the on/off switch at the "toe" position of the pedal sweep. Instead, it was switchless--it only turns on when you're stepping on the pedal. That might be OK for a wah, but with a phaser that means you can't turn it on and let swirl at one particular speed--you have to step on the pedal the whole time you want it on.


a decent pedal

Alright this pedal is pretty nice although a little pricey. My friend owns this pedal and he has used it on many of our gigs. I must say,there is a spot below the heel end of the pedal you can tighten the pedal tension(so it doesn't slam back down onto the bypass switch). Overall its a nice pedal, but I would reccomend any of the other phasers(phase 90,100,and evh phase 90)over this mainly for the price.

The best-built pedal ever to be so worthless!

By SickofLameGear

from Blossburg, PA

I returned this pedal fast... why? Where do I start? How about opening the box, to find scads of slick promo junk for other gear -- but absolutely no manual or instructions for the pedal that was in the box!I'm pretty smart, and was very excited to try the pedal, so I set it up anyway. First, the "variable speed" foot pedal is only variable while my foot is on it. Then, foot removed, it slams back down onto what? The on/off switch! But I don't want it to always turn off, I want to rock the pedal to a variable and let go, or rock it through the upper range during a passage and let it return to a moderate back-pedal setting. If the on/off switch were mine to control, I might have kept the pedal.Bottom line: unless you plan to live with your foot on it, this pedal is completely useless. It's also very noisy the moment I activate it, no matter the setting. I was more eager to get this pedal than any effect I've bought in a long time, and my disappointment is every bit as extreme.I may not even bother with the way cool Phase 90 that I should have bought instead. I'm that mad.


Cool phaser

By fazermandel32

from Illinois

I first saw this pedal at a music store when I went visiting my relatives in Washington. I thought to my self when did they come out with this model because I have never seen it before. Anyway The pedal has the sound of a phase 90 with a foot controller pretty cool. You can get some pink floyd and hendrix sounds. It's kind of like the uni-vibe.


Does what it was made for

I have had this pedal for about two months now and I love it. It is definitely a specialty pedal and you should not buy this if you want a regular phase 90 or a pedal to phase for long periods of time.
