MXR produced an updated version of their Phase 90 pedal, that celebrates Eddie's use of the pedal in his early career, with a new design similar to that of the earliest paint job found on his "Frankenstein" guitar. It also features a "Script Logo" phase tone— truer to the version popularized by Van Halen— and a "Blog Logo" phase tone that's more suited to modern sounds.
I had stock Phase 90 which in general is great pedal, but this annoying volume boost (or even a distortion) can be pain in the ass, so R28 mod is necessary to get things right. This EVH Phase solves all problems since you can immediately switch from block logo mode to script mode without opening and modding circuit. As we speak about tone and overall quality - 5 stars, this pedal literally sings both on clean and heavy distortion.
