Lots of excellent suggestions already posted here. I'm currently using a dizzy tone fuzz (ppcb gnat) and a phat phuk b on vero for my main dirt tones. Chuck d bones bass kliché and curds & whey are also on my board. There's a madbean gas tank too but that's mainly an add on to my junk trunk build. That combination is awesome though.
In my practice nook(aka workbench, aka laundry room), I reach for the ppcb akronym and effects layouts grizzled grime a lot lately. Moonn lofran is a staple for me that got bumped by the dizzy tone. It's the most recent bmp cousin to grace my rig. Frantone muffs are excellent for bass in general. Been playing with my sushibox bassdude a bunch too.
