Just watched this for a second time and noticed the bass rig in one of the Otis Redding TV performances. The black player obviously wasn't Duck Dunn, but he used a Sunn head and cabinet, most likely a 100s with one of the single-15 bottoms. Sounded nice for the era, not biting but clear and smooth. Didn't note the time count, but I can find it easily enough if anyone's interested.
Warmest regards,
