Right now I'm running phaser early, fuzz>phaser>dirt. Then chorus and flange are right before delay and reverb. I usually only use one, two at a time at most. Everything in front of amp. I'm relatively new to the modulation game, and still dialing it in, but so far I'm getting the sound in my head this way, and def prefer phaser before dirt. I like the subtle thing.
BTW thanks for making this community whoever
