Now show a still photo from the Cream Albert Hall show and look at Ginger Baker’s setup— most did not know that Baker became deaf— so the bass reflex LOUD signal was sent over a heavy duty 18 inch woofer as well as a equalized signal which vibrated the entire drum “box” and through his chair. He played from the sensation of the sound of Jack Bruce’s bass and also Clapton’s bottom end frequencies. Pretty clever. So was the use by Clapton many years ago on up to 2005 of running his guitar through a Leslie organ cabinet (with spinning speakers)- which can now be created in a electric signal stomp box (but Clapton had to wait until the full house signal came down enough on sustain to stomp the actuation button for the Leslie (and uh, not blow most of the house system). So have learned from major sound people in nashville (old timers).
Here is a video that shows both Ginger and the Leslie effect in one video “Badge” (the miswritten title from studio notes- Bridge looked like “Badge” who knew?):

A better view of the set up tan large cabinet on the drum box and precisely placed drummer seat (bolted?).
