I saw him w/Clapton using the Eden rig, and later with the Aguilar rig. Nothing really different. And his recorded sounds going back to the Trace/Elliot rig didn't sound any different than either the Eden nor Ag rigs. Gary Willis also doesn't sound different to me when he switched from Eden to Aguilar either.
Pretty much East's sound is (in order of importance) his brain and ears, his fingers, his custom-made EQ, the Avalon DI that's been in his live rig for a L O N G time, his basses, and his strings.
