Hey man. I chose a kick sample from my library that worked best with the context of the drums. Other than that, there are no other samples whatsoever. Not even blends or anything. Snare and toms are 100% what was originally recorded.
After that, tons of EQ, lots of plug-in gating and manual gating to deal with the cymbal bleed and such. Otherwise, it’s really just EQ and compression throughout. On the room tracks I did saturate and distort them a bit but that’s a pretty common thing to do.
