When I saw his GC session in Los Angeles, I managed to get a photo of his pedals prior to the start. He was using a wah, Vox Satchurator protptype, Dunlop Octavio, and a
delay pedal, all into the
JSX head and a single 4X12 cab. Very simple set up, but it sounds like the Octavio was used quite a bit on the new CD. You can definitely hear it on Musterion and Overdriver.
