Didn't try the Ashdown cabs as I was head shopping rather than cab shopping, so I just plugged into an Orange OBC410. They only had Orange gear in their soundproofed room and so I just chose something that was available rather than lug something else across the shop!
Just checked the video, the drive sounds much nicer when it's just on the edge with the gain around noon, he overcooked it a bit there and didn't show much gain variation.
