Dan Donegan (Lead guitarist)
Dan Donegan is the bassist for the band and from what I know he's the second bassist they've had. his trademark is his hair which stays in the same style most of the time and is usually (except in videos) seen wearing sunglasses. He is seen in almost every video and is probably the coolest member of the band.
Steve Kmak (Bassist)
not much is known about Steve because he doesn't do much talking to the press and he is usually too busy with the band (trying not to get dropped out) to do much except go home to his family. He works extensively to keep the band up and is the more muscled man out of the others (or so he says) and when he has time he either works out or he is busy writing the notes for another song. He was replaced by John Moyer from the Union Underground.
