It totally depends on the context of the gig. If you are the headlining act at a classy venue, then yes, there is a chance that a percentage of the audience will be there specifically to bask in your bass artistry. In that situation then your flanger or whatever is an important part of the show. And presumably at that level you are either running your own sound or have spent time with the soundguy discussing your mix. (A great way to do this is to give the sound guy a copy of your CD in advance of the gig and tip him a few $$ for his hard work and accommodations.)
If it's a 45 minute set at a dive bar battle-of-the-bands, then nobody is there to hear the flanger on your bass, they want to get drunk and have a good time. Plug into the stupid Countryman DI or whatever and make the people dance!
