That diagram is NOT of *my* pedals - LOL! It's a diagram I found ages ago that attempts to show the generally agreed upon placement and order of effects/pedals, with a note (IIRC) that there are no rules.
99% of my effects are VSTs. The other 1% hardly get used. I think I have 3 pedals that get dragged out/connected every few years to see if my tastes have changed.
What I'm doing now is experimenting to see what all I can get out of my gear.
Beep - interesting about your bass output levels. I have a Peavey Milestone bass I bought last year that I haven't done much with yet. I'll hook it up and see what it does. Just thinking out loud ... I wonder how much the freq range of the instrument has to do with it.
