the exact same back synth or whatever it's called as the comet?
There are no keyboard or synth sounds on this EP; it's all guitar.
(but yes, that guitar sound is on both tracks)
EDIT: The source for that info is their FB update;
"we are getting awesome reviews for the new EP, thank you to everyone it means alot, but on a personal note I want to get this out there as I have seen it in almost every review that there is NO KEYBOARDS on this record, every evil sound you hear on this record is from the guitar and my amazing effects pedals, I was very proud of the sounds we came up with and worked hard at it, so for those listening there are no keyboards on this EP...I knew I should have put it in the liner notes!!! I hope everyone enjoys the pure organic evilness..."
