I have the MXR reissue (not the EVH painted one). I use it mostly for Van Halen songs, and it is great for that (and some Barracua by Heart). I also use some the MXR flanger for clean tones as well (some police).
I have a Digitech flanger (purple) which has lost of options. Are better than others. But it is digital, and it does not like gain pedals in front of it.
I have owned others years ago, that I should have kept for the resale value, but no flanger for years until I got the tow mentioned above.
