Hello dobro (nice work on latest song by the way).
Frequently. I could have any number of reverbs (with various sidechain, EQ, decay, automation etc.) on any number of tracks if that's what I think is necessary or just one if thats all that was needed (if anything it's rare for me to use just one).
Same with compressors, depending what I'm trying to achieve. Also I might us a limiter directly on an instrument track to catch peaks as well as on my master bus. Multiple limiters, we all do that don't we.
