Bonus Recommendation: Reverb and Spatial Effects
Reverb is one of the fastest ways to give your mix depth and dimension. Used well, it creates space around instruments and makes a track feel alive. Used poorly, it can turn everything into a muddy mess.
Two plugins worth calling out:
- FabFilter Pro-R – A flexible, modern reverb that covers everything from small rooms to huge, lush ambiences. It’s clean, intuitive, and fits almost any mix.
- Valhalla Room – A go-to classic for adding size and character. Simple interface, great algorithms, and a price that makes it hard to beat.
The trick isn’t just choosing the right plugin, it’s knowing when to step back. A touch of reverb can open up your mix; too much can bury it. Subtlety almost always wins.
