The radius on his fretboard looks ridiculously flat. You'd think that he'd be using a more tightly bound fretboard for all the sweeps and shred shit that he does.it was definitely the Caparison btw. The pics on caparisons website have his model with the dimarzios in it . I got the pic I posted and the specs from the band's site:
