sorry i just realised this is in the dj forum not the production forum so you dont mean in a track apologies force of habit

i tend not to use effects much in my mixes but reverb can work well when cutting a section in and out to leave a tail behind also a beat synced delay 1/2, 3/4, 1/1 etc can work well for adding kicks in time etc also when faded out into a delay you can get good results
