When you want to make something sound bigger in your mix you’ve got several options. You can crank the bass, double-track it, or you can use something like The Fattener.
It’s a pretty simple concept: The Fattener delays one side of the stereo spectrum, making things sound bigger. Simple as that.
You can ‘tune’ the delay, as well as control how much is added to the mix. That’s it. It works.
