Part 3. How to Choose the Right Saturation Plugin
After reviewing all the plugins and weighing their pros and cons, it's time to pick the one that best suits you. But you can't grab any saturation plugin and hope for the best because the wrong one can mess with your mix or eat up your CPU.
So, here are some factors to consider before grabbing that saturation VST plugin:
What's Your Genre?
Some saturation plugins work better for specific genres. Smooth tape warmth fits lo-fi and soul, while gritty tube distortion hits harder in rock or EDM.
How Much Control Do You Want?
Do you want something quick and straightforward, or a plugin packed with tweakable settings? Some tools are made for fast results, others for deep sound shaping.
Free or Pro Level?
There are plenty of great free saturation VSTs out there, but if you need advanced features or studio-quality tone, a paid one might be worth it.
DAW compatibility and CPU use
Don't underestimate system requirements. Check if the saturation plugin plays nice with your DAW and won't slow your system down. No vibe is worth a laggy session.
