I know G2's on toms, with G1's on bottom. Lemme see... EMAD on batter of bass drum, and I think the EQ3 resonant, but I'm not completely sure about resonant, and plus I think his kick is triggered. His snare has a Rock AF (close to a marching snare head). Dunno about the snare side head.
His tuning... well, he uses smaller toms (10, 12, 14... he might have a 13 i dun remember), and you don't really hear very high pitches, so I'm guessing he tunes em medium low- low. Personally, I'm not a fan of his drum sound. His snare drum and kick sound kinda weak... The snare drum is kinda lifeless. But I'm sure thats because of the Rock AF head, which is Evan's heaviest and msot focused snare head (according to their chart, even more focused than a hydraulic

), close to a marching snare head.
Btw, a great drummer in a great band. System is my favorite band, and John Dolmayan has become one of my favorite drummers.
