Hey, thanks! All done on my PC using Reaper (
www.reaper.fm). I use Superior Drummer for the drum tracks and do guitar, bass and vocals direct along with a variety of plugins.
For the vocals, I double the main tracks, panned 100% left and 100% right, and compress the shit out of them. I'm not really good with compression and it's mostly guesswork, but it seems to come out right. Glad you liked it!
