nord micromodular is probably one of the best effects out there.
it doesnt do reverbs and delays (easily), but you get much more than effects with it, including learning how things work.
cheap for what it does, compared to available pre-determined gear and their prices.

micro mod makes a hell of a pedal.  i miss mine but life goes on

but you also didn't say what you want the pedal to do so you're dead to me OP

i've got a zoom ms-50g that's pretty great. can run up to 6 different effects at once and the newest updates give you access to 172 different effects or guitar cab emulators (mostly effects, forget how many cab emulators) gives you a ton of options in a single pedal

+1 for this one, too. It's also on my guitar pedalboard. I call it my flair pedal. I'll never use it as a replacement for an actual Big Muff or something like that, but I don't really need a dedicated phaser/reverse delay/chorus/etc each taking up space in my setup.
