I'm still using my 16.0.2, so can 't you the exact effects I use since the names may be different. I use a combo of Studio A SMALL ROOM and Ping Pong Trip PINGPONG DELAY.
You can experiment by hooking up the mixer with a pair of PAs, then listening to each effect to see which one sounds best to your ears. Don't use headphones, since the effects heard thru headphones won't be the same as in real live.
