This is a bad demo even by demo standards (demos are almost always bad) but this thing could probably sound fine in the right hands.

Also I like how they state "only compression and limiting were used" as if those didn't have a huge effect on how something sounds.

This price won't last forever

This is only marginally worse than the hideously overmodulated dubstep basslines that are usually squeezed out of wavetable synths like this.

Actually, now that I think of it, I've never made it through a Skillrex song, but I've listened to this at least 5 times.
