Used for "Makes Me Wonder", as stated by mix engineer Mark Endert in this September 2007 Sound on Sound interview.
Drums: Alan Smart C2, SSL EQ, Lexicon 480L, Tube–Tech LCA 2B, Logic Compressor, Waves PS22 Spreader, Focusrite D2, Tech 21 Comptortion, URS A–Series EQ.
“Basically I wanted the drums to sound fat and loud. A lot of processing on the drums is done on the SSL, using EQ and compression. I also love the Alan Smart C2 compressor, and I bussed things like the kick and the snare to the C2 and returned them on two separate channels. They really are spanked pretty hard, so it really punches up the drums. The C2 is set to ‘crush’ mode, which completely annihilates all the transients and brings up the air. Like with most of my stuff, I’m sure the attack was set pretty fast, to probably 1ms, and the release was pretty fast as well, again to bring up the air. It was a completely crushed sound that I blended in sparingly. I used some Lexicon 480L reverb on the drums, and the three room mics were hit really hard with a Tube–Tech LCA 2B compressor to bring up yet more air. My drum loop also had serious compression, but I think that was done in Logic, using either their Platinum or their regular compressor. I didn’t add anything to the loop during the mix.
“I added a lot of bottom to all the drums, even before they hit the SSL. I had programmed a clap sample in Logic, but I felt that I couldn’t really hear it above the snare, so I put it through the PS22 Spreader and suddenly it was there. I also EQ’d the claps very severely with the Focusrite D2 plug–in, boosting around 80 and 134 and shelving some top off above 12K. I wanted the beats to be fat, without too much transience. I was trying to see whether the claps could withstand having lots of bottom added, and it sounded good."
