It really depends on a lot of things, but as much as I like effects I don't think they necessarily are the answer for situations like these - It's much more about how you play during these passages. Too much effects may drive attention away from the other guy's solo, or literally drown it out. The whole band should be involved in the strategy chosen for these passages.
That's MHO and of course, YMMV.
