well technically my POT is my OD, so in front of it i have a sunlion (fuzz, then treble boost) and after it i have a RAT, which is my distortion, but honestly i run it pretty darn clean. If i was going to ever run anything after it as my "always on" i'd put a "sweetener" like a nice compressor or something.
I've tried a couple different pedals to stack with the POT, but right now I'm digging my Walrus Audio Mayflower and going into a DRRI. Some might argue the Mayflower is very Timmy-esque, but I like it with the POT more because it's a smoother gain and it has great bass response.
Well, right now I'm stacking everything with a Timmy. That stays on the board, and I have one additional spot to swap in one of my other OD's depending on how I feel. So the POT gets stacked with that, POT > Timmy.
But maybe I'll try stacking the POT into my Zendrive..
