[HAM] CT's instrument setup

[LJRose]

I followed the link posted here to the Keyboard video clips of Chester 
Thompson--they were great.  A brutal comparison of the sound of the B 
and XK3 (sans Leslie), but that's a highly charged issue best avoided.  
My question is regarding CT's B.  He's got stuff on the left side "end 
blocks"--looks like tone controls.  Any ideas what they might be?  Also, 
(a potentially dumb question) is he getting the overdriven Leslie sound 
because he's pushing the Leslie really loud or might it be taking place 
in an earlier stage?  On my home setup, I've never gotten the Leslie to 
scream like that, but I guess I've never put everything on 10 either.  
The volume would seriously bother the neighbors!   It didn't seem that 
CT's speaker was incredibly loud--he was sitting right next to it, and 
the audio didn't seem to reflect a vast difference in signal from the 
conversation segments to the playing bits.

Also, just in case anyone missed this link

This has been an amazing eye-opener for me.  I'm sorry to admit my 
Hammond history is so lacking that I thought Keith Emerson "invented" 
the balls-to-the-wall Hammond sound.  I had never heard of most of these 
players--I'm spending time today tracking down Sonny Burke!

Thanks to all who maintain and support the forum.
