I'm Pretty sure this is correct 
You have to tune down a half step (Gb, Db, Ab, Eb) (GC is a band that tends to tune down a half step most of the time)

You guys really have to listen closey. I've been plyin' this way for a long while and I can tell you it's right. I'm also sure it's tuned down 'cause not only does GC do that on most (not all) songs, but they did put the tunings in a guitar part (only guitars) in Guitar World. Check it out, and listen carefully. By the way, please comment if you do find something wrong with it.
