I like my phase 90 (script version) before dirt. It's subtler, more natural and kinda pink floydy / phishy. Every once in a while I'll try it after dirt and it doesn't sound as nice to me.. Kinda artificial.
I'm still figuring out where to put my Mooer Elady (which I use for subtle chorus sometimes).. It seems less picky about pre/post dirt but I could be wrong.. Still figuring it out!
