Agree, leslie off, distortion, optional vibrato. It makes quite a cutting bright sound in a band situation, and sometimes I prefer this to using the Vox/Farfisa settings on the Nord. My favourite from that era is the Yamaha YC organs run through a tube amp (I own 2 of them!), and you seem to get a bit closer to this sound with a non-Leslie Hammond.

; I sometimes used his NE2 setting: 888004043.
There's a fuller setting I preferred with a few scoops cut out of the high drawbars but I can't quite recall what it was. I'll see if I've got it saved on my NE5 when I get home.
