I wonder if he is splitting his signal off and sending upper mids and highs to a guitar signal chain and running his effects on that, while sending the rest of his signal to a bass rig. Looks like he is using digital stuff and that would make a split signal chain fairly easy. I tink dUg Pinnick does that, or used to do that.
