Something that I love about dance music is the exaggeration. The reverb is not just a tool - it’s an instrument. It enhances everything.
The delay is not just a rhythm - the delay enhances the rhythm.
Some might argue that isn’t that the role of Delay anyways - but EDM uses it extensively.
For reverb - check out Don Diablo’s Forever. The reverb that comes in the drop on that guitar-ish riff.
