Hi all.
I'm talking about deep low downwarding sound that can be heard in many tracks produced by Joey. For example: Of Mice And Man - O.G. Loko (2:50) , Asking Alexandria - If You Can't Ride Two Horses At Once... (2:05), Chunk! No, Captain Chunk! - Captain Blood (0:00).

Is it heavily processed bass guitar or kick drum hit? Or it generated by synth?
I tried to make this sound and all i've got sounds really lame :(
