This is a simple setup: 1 on/off toggle, 1 knob to adjust speed, 1 button to change from tradition mxr phase to EVH phase. It is said to be true bypass.


Controlling the sound is ridiculously easy; simple speed control and EVH switch. I never read the manual as operation is completely intuitive. I typically run the phase with a speed setting at 8:30 and the EVH button engaged. Special wacky phase tones I set the speed up to 3 or 4 o'clock.


I use this pedal with a variety of guitars in a variety of tuning, including Gibson Les Pauls and Fender Strats. I put it towards the end of my pedal board: tuner>Wah>OD>Phase>Noise gate>Amp

In bypass, the pedal scores high marks in keeping the signal pure, avoiding the usual tone suckage many other pedals present. Engaged, the phase sounds are fantastic!


I was hesitant to buy this pedal, thinking that the lack of controls would be a huge disadvantage. I thought a dry/wet mix feature and depth controls would be absolute necessities, so I hesitated. But I love EVH, so I made the plunge; I am thrilled i did!
Once plugged in, the simplicity becomes a HUGE asset. The depth and wet/dry mix are actually perfect, as the tones of the phase yield a present effect without ever approaching an overbearing splash of "too much". The difference in the standard vs EVH push button are gentle, so typically i roll with the button engaged to EVH. The speed settings are easy to find great tones, as it sounds great in many areas, depending on the material. This pedal has become a set and forget it, as the effect sounds so great delivering classic EVH vibe. It is a pleasure knowing the effect will always sound great and you can spend more time playing and less time tweaking endless parameters.

I usually find effects annoying and enjoy straight ahead guitar to amp tones...but this phase has a soothing effect on the listener making it real easy to jam for sustained periods without inducing the usual fatigue associated with phasers.

MXR knocked it out of the park on this one and I am sure to try the EVH Flanger at some point in the near future.
