The “modern” part of Gill’s rig is centered around these two MacBook Pro computers running Apple’s MainStage. For each song in the set, Gill has a specific patch that covers the tones he will need. The signal chain is rather complicated, but here’s a quick overview: It starts with a Boss TU-2 tuner before splitting out into a pair of Focusrite Scarlett 2i4 audio interfaces. Those interfaces are connected to their own computer via USB. The 2i4s then each feed a Radial ProD2 DI which gives the FOH a MainStage-only mix. Each of the DI boxes also are connected to individual Radial ProRMPs, which feed the Peaveys.
