The official line-up for this album is Seth Putnam (Vocals), Tim Morse (Drums and Vocals on #39) and Scott Hull (Guitar) - Scott (from Pig Destroyer and Agoraphobic Nosebleed) had recently replaced John Kozik as the AxCx guitarist.
However, according to Seth, he did most of the guitar playing and a lot of the drumming, as Tim could not play what he wanted him to and Scott was too new in the band to know all of their songs, as well as the fact that Seth just wanted to play guitar.
