Rated 4.5/5

Great pedal

there is something that no digital pedal does yet well and that is to emulate modulation effects, use both the Fractal FM3 and the Kemper Stage and both come close but not quite, I thought the sound was going to be too excessive or too light, but the ending is just what your ears ask for. countless recordings recorded that sound in your memory so it is difficult for it to sound bad to you, I only give it 4.5 because I would like them to find a way to add some extra function to this case, I know that the mini P95 exists but I do not like the mini pedals and the P100 is already too big
Rated 5/5

This is your phaser

Super simple. Effortlessly get a perfect phaser sound and just set the speed to your liking. I almost always use it with the speed all the way down to get that sort of incubus phaser sound. I sometimes like to set it to 3 o'clock where the speed is fast enough to give solo notes sort of a rotary sound which can also be really cool. Also Van Halen.
Rated 5/5

That 1 thing missing from your EVH solos.

I am an unabashedly intense EVH freak, and I love his guitar tone and skill above all. I have many stories to tell about this pedal, but my first is my favorite. I had asked my guitar teacher to teach me eruption, nd he told me to bring my pedalboard. I had a phase 90, as it is one of the most Iconic pedals ever made and was one of the first pedals I ever purchased. When we got to the tapping part, I learned and played it, and he said now do that again. As I began, he clicked on my Phase 90 and placed it at a low setting. It completed the solo and made me feel like a guitar god. it was euphoric. I really can't recommend this pedal enough, whether you are looking for a simple compact phase to start out, are a pro who needs a versatile box that saves board space, or are a Van Halen Maniac like me, you need one of these little guys on your board.

The wonderful sound of EVH!

Simple ,straightforward, and to the point! This is a pedal adds the classic EVH and Rush sound. Here is how I have this setup. First my MXR Micro Flanger, MXR Phase 90, Morely Classic Wah, Ibanez ts9 Tubescreamer, Boss EQ ge-7, Digitech Whammy 5, MXR Chorus Analog, and Pigtronix Gatekeeper Micro at the front of the amp. The only pedal in the effect loop is the Pigtronix Emanator dely. The Flanger and Phaser is at the front of the amp because I find of them to have more control after all my pedal arrangements. This pedal made my sound so much better!
