All natural kit. Absolutely no replacement/augmentation.
This whole EP was done with the idea that there would be no pitch correction, TCE, sample replacement/augmentation, or performance-altering editing.

Now those are some tight-ass vocal harmonies and doubling. You don't hear that much these days without having a shitload of Melodyne or AutoTune and a dose of Vocalign to boot! You can tell the vocals are very natural, which I love.
