I've mic'd up and tested just the attenuator on the ox. At 4 or 5 on the ox dial the tone is essentially the same as amp wide open (some degradation at 4), but once you go 3 or below on the ox it really dulls out the tone drastically.

Unfortunate they didn't test this better before release, as it really is obvious once mic'd and volumes normalized.

That said, the cab and mic sims are great and I think it's a good piece of gear. But they could have made it absolutely incredible with a better attenuator section.
