A chorus is an effect best used in moderation IMHO
I keep mine turned way back and at a very slow sweep, almost can't tell it's working as opposed to a big swooosh! of 80s sound. Used under a slow ballad it just gives a little fill and with an octaver adds a little sweep and shimmer. Still at best it's a compromise as opposed to a Uni/Micro Vibe running on reduced voltage (what I usually use), but the original post was about a three pedal basic setup.
All effects have their place and never thought of them as being a cover for bad technique ... but to each his own I guess.
Under the best circumstances they are worked into the music so well that the audience (as opposed to other musicians) are blissfully unaware that an "effect" is being used at all. The Pino Paladino clip is a perfect example, just can't imagine anyone hearing that, thinking, hey I wonder if he is using a Boss OC-2 on that? Even a good fat overdriven basic rock tone ... is that a real 72 SVT or a VT Bass pushing a GK 1001rb, is not a subject you will likely hear the crowd talking about.
And as it has been stated you use what "your" music calls for, Reverb, delay and a Q filter are not on my list of needs but I can see how it could fit in to someone elses.
... The way I use effects the audience should be un-aware of them and the sound just fits the tune.
+1 on all of this. I think these effects deviate less from your clean tone, which in my case is a good thing.
